I am looking at the world products windsor heads for my 67 289 and was curious if any one has any advice. Should I go with the windsor sr or windsor jr.

Nash,Go with the jrs for the smaller combustion chambers. The larger intake valves won't help you w/your 289. IMHO  SteveW

Nash,
I have the 58cc WP head on my 289 worth it..add the roller rockers and your set.SteveW correct on the 64cc heads they will drop your compression so be sure to request 58cc.
In doing the comparsion between reworking a set of 351W's and ordering the WP58cc's I came out bucks head ordering the complete 58's sam

Do the windsor jr's have the same relocated spark plug postion as the seniors? I bought a '69 Fastback with a 302 with Windsor sr's on it, and 2 plugs were impossible to change w/o removing the headers.

Hooker Super Comps work with the WP heads. The regular Comps do not. As for going with other brand headers, who knows what will work. Check with the manufacturer.Good Luck! ------------------

I had a set of regular Hooker Comps in my 69 with a 351W and WP Sr heads. They fit, but it was tight. I did use Accel shorty plugs (#276S) to get a little more clearance.Don't know how much truth there is to it, but I've been told that the problem is with WP heads made before spring of 1997. They were supposed to have made a slight casting change that moved the plug just a bit to correct the problem. Mine were made in this time frame and they work. I buddy of mine bought a set of used WP heads that were made in 95 or 96. He used them in a a 66 Fairlane and had big problems getting headers, so there might be some truth to it. I use the same heads now with Hooker Super Comps and there is plenty of clearance. Later, David Cole

fordmuscle.com did a decent review on about 8 different sets of heads, everything from simple street heads to fully ported/polished race heads. If you haven't purchased anything, I would give that article a once over just to make sure that those heads (Jr's) are the ones you want. Some of the newer designed heads have slightly better castings that improve air flow on both the intake and exhaust ports which will translate to more HP if combined with the right cam/intake/exhaust. I'd personally go with the avenger or twisted wedge heads IMO. Also, F-P-S.com is having a deal on avenger heads last time I visited their site.

I am looking for something in the more affordable range like the world products windsor jr cast irons. What other options are there for 67 289 motor with hooker comp headers that would be in this price and performance range?

If you want cheap, check out PAW's ported '65 heads. They sell 'em with the intake and exhaust sides ported, and with 1.94" intake/1.6" exhaust values for only 500+ bucks. And since they use the early castings you get the low chamber volume that you want. If seen those things advertised in their ad's for years now but have never seen a magazine do any reviews on them. I have however seen reviews on home-ported '65 heads and the results are very comparible to the Jr's.Don't forget to plan on being raked over the coals for shipping on cast iron heads as well, especially if they ship them seperately.

If I dont go that direction, what would be a good set in the $1000.00 range would the edelbrock rpm work with my setup? It seems about time I add the windsor jrs with a set of new headers I would be in that range.

That is comparable to all of the aluminum aftermarket heads, which generally range from 900-1100 dollars. I like the Edel RPM's for a more mild motor, since you have to get cut pistons to use the large valve sizes. They also come w/ pre-helicoiled stud holes so you don't have to worry about ripping out the threads when torqueing down those studs. I would choose unassembled for whatever model you go with, especially the twisted wedge heads which I've heard come with below average quality valves/springs. Ofcourse a sales man told me this, so it could have just been his way of convicing someone of another sale. Anyone else heard anything about this?

I have never run the World Product heads, but all the ones I've seen have had some casting irregularities, such as flashing and casting bumps in the ports/chambers. I am using a set of Edelbrock RPMs on a winsor now, and they also are in need of a little work. Both valve seats are shrouded by about 3/16" with a couple of sharp edges where the seat recesses were milled. The ports/bowls have some casting bumps that I blended as well. The factory did some port work on these as they are the RPMs but they were'nt blended as well as they could have been.

I already have flat top pistons with valve reliefs for what I believe to be a 10:1 compression ratio. Would it make any sense to go with the 2.02 valves since I could probably stand to lose a little compression ratio? Also would this be enough clearance for the valves or would they need further modification?

I built my motor with the larger valves and had the heads slightly milled(TFS Street Heat). I actually had the heads fully ported and the intake valves increased in size to about 2.04. It depends on what you are looking to do and what you want. It might hurt you a little on the low end but I was looking for high end power. My car pulled to about 6800 rpm. quote:

Looking for advice on the aftermarket heads for 67 289. I am trying to keep thing to around 1K. I am torn between edelbrock rpm heads or world products windsor jr Iron and in addition changing to the roller rockers. I have an edel rpm manifold with holley 600 carb and mild upgrade cam and hooker comp headers. Car is a street only but is not a true daily driver either.

They are a little over 1K but I here good things about the CNC AFR heads from the 5 liter guys. Since they are factory ported they have great flow numbers. Considering they are ported the price is good. They have both large and small chamber heads.The Edelbrock heads are said to be very well finished right out of the box. I haven't heard anything about the Windsor Jr. heads. I would suggest that if you intend to stay with a mild cam and a 289 that you stick to the small chamber heads of whichever variety you like. The larger ports and valves won't make a difference with a medium sized cam especially on a 289. You are basically looking at a 6000 rpm redline and it won't matter which you choose. I went with larger heads because I didn't know what I would do down the road and I had a high reving motor. It turned out well though since I am now going with a stroker but I won't need new heads. Good luck but you really can't go wrong with any one of the heads you are looking at. quote:
