I'm rebuilding my 1966 289 and am looking at heads. I know that 351 heads are the way to go but that you can lose compression due to larger combustion chambers. What years of 351 heads are the best for a 289? Would I be better off locating a set of rebuilt 351 heads versus having my 289 heads with 120,000 miles on them rebuilt? I like the sound of the $1500 289 rebuild in the thread below, how does one contact the Moneymaker shop about getting a set of the 11:1 Badger pistons and thin metal head gaskets?

Alex wwill be by later for sure..
How about looking at a set of Windsor Jrs rather than a costly rebuild of the 289 of 351 heads...
cross check the total cost & compareOh an welcome to MustangsandMore

The good 351w heads are '69 & '70 castings. I think they have around 58cc combustion chambers. I had .030 milled off a pair and it took them to 54cc's which are roughly the same size as 289 hi-po heads. 10-1 compression with flat top pistons. The windsor Jr's are a better choice though.  SteveW

What is the cost comparison for windsor Jr's compared to stock 351W heads?

The 69-72 351W heads have 60.4cc chambers and 1.84?/1.54? valves, but I don?t know if they flow any different

Sam,
when looking at reworked 351 heads vs the Jrs I found that I could save over $250 using the Assembled Jrs-using Crane roller rockers and was ahead in performance to boot.

Where's a good place to buy the Jr's from? Summit Racing lists for $1079 if I read the online catalog correctly? That's way too much. I already have a set of GT-40 valves (same size as 351W), and new springs, retainers, locks, seals, guide plates, etc for the 289 heads I have will be under $200 from Summit. (I'm not including lifters/pushrods/rockers because they will cost the same regardless of what heads I use)My machine shop guy back home in NC rebuilt my toploader for $100 labor, and rebuilt my 4100 for $40 or $50 labor, so I figure I'll get a pretty good deal having him work over my 289 heads. He's done all the work on my dad's mustang too, tranny, rear, etc, and we always get a deal.Sam, 351W heads were going to run you $750?? If so, I gotta stick with what I got, my wife just won't let me go for that kind of money. (Even though we CAN afford it...  )

Sig,Like Sam said the assembled Windsor Jr's are cheaper than a 351w head with new springs, guides, etc and flow a heck of a lot better! They are the low budget way to go for a street/strip motor.  SteveW

Just be aware that these come with tiny 1.25" valvesprings that will need changed out with anything other than a stock camshaft.They will need the casting flash smoothed out with a grinder, and come with fairly cheap valves, etc. However, for the money, they are a decent head. Just don't expect to be able to take them out of the box and install them straight onto the car. Good Luck! ------------------

Aftermarket heads are best, and as far as value is concerned Airflow Research is tough to beat. You call direct, tell them your engine combo and cam specs, and they set the head up correctly for your engine. You just take them out of the bag and slap em' on the engine. They have a listing of all the gaskets to use, head torques, plugs, etc. They use quality parts. The CNC port work is OUTSTANDING. It extends pretty much the whole length of the port. It's not that cheapie Edelbrock crap that just squares up the port entries and exits. It's REAL porting.You pay a couple hundres extra dollars, but they are well worth it! They will help you choose between the 165's and the 185's, as well as combustion chamber size. www.airflowresearch.com Good Luck! ------------------

Mike,They will work fine with the 270 Comp cam that Sig is going to use. As they did with Sam's motor. Not a race car just a healthy street car. SteveW

Does that estimate include the heads and all work needed to bring them up to snuff or is that price for just the heads alone?

I wrote that assuming that the windsor Jrs would be $1000, turns out jegs has them for $800, so figure they'd actually only run $550 if Sam was going to only save $250 by using them. The specs say it those springs can take up to .550" lift, which would be fine for the 270S, and it says it has stainless steel valves, which cheap or not I'd guess would still be better than stock valves? $800. I cannot believe I'm actually contemplating going for those windsor jr's now. Thanks alot guys, my wife is not going to want to hear this one. In case you haven't figured, she's real stingy with the money. But, at least we have no balance on the credit cards and the loans are all almost paid off. I asked her how much more a month I could spend on the car after the loans were paid and she said spending any more than I already do would be "obscene". LOL, I'll hold off on that argument for another day.

Cost of pr.heads and machine work to bring them up to snuff for the cam and other goodies added..the Jrs ran appox $700 assembled 2 years ago...should be in that area now..All I needed to order was the Crane roller rockersSam I also used the rebuild kit from Summit with the 9.7 to 1 pistons All parts for my engine with exception of water pump/fuel pump ect were bought from Summit.
