Hi Guys,
I just saw a set of the 180cc Pro Topline heads at a friends shop today. These seem to be the best castings as far as finish goes I have ever seen. There didn't seem to be any clean up work needed in the bowls or short turn areas. He hasn't had them on the flow bench yet, so I don't know if they flow as advertised. At a glance these heads seem like a great deal for the money.

I think you can get set (complete) off Ebay for $1200 or so. I hope they are equivalent to the AFR 185cc heads for less money.
You realize that the AFR heads are CNC ported, while the Pro Topline are "as cast".

Scummit sells them for $990 bare, and $1200 and up complete, depending on the springs they come with.It doesn't suprise me the casting quality looks very good. I worked on a couple of sets for SBC's back in Iowa, and they were by far the nicest castings I had ever worked on, and that list included, Dart Iron Eagles, Bowties, and World Products heads.

I agree, aluminum expands at a much greater rate than steel does. There are problems associated with running alums on an iron block, leaking coolant would be one, tearing up head gaskets is another. However having 50lbs off the nose, and being able to run higher compression is a benifit of using aluminums. ------------------

thier site lists the iron ones as $697 unassembled per pair, $349 each.may have to get a set of 58cc ones for my car, that's a steal of a deal if they are half decent. And with them being iron it should be allright for street use. Summit lists the 200cc bare for $330 each bare, but the 180cc don't show up. And even the 200's arn't available  you get a message saying "The part you requested is no longer available from Summit Racing...." ------------------

Dubz,
If you would move down south, you could run aluminum heads on an iron block and have no problems.

Lots of new cars come directly from teh factory with aluminum heads on iron blocks. Everthing from 4 bangers, V6's, and 8 cylinder motors are made that way now. Personally, I think it's nothing more than an old wives tale that it's a problem using aluminum heads on iron blocks.

I agree Rob, That's a 90's problem. Every fast car I see has aluminum heads on it. (except for the stock eliminators anyway) but who can afford their iron heads w/o a sponsor?  SteveW

-25* F (-32* C)is the temperature out at the moment according to the weather networks "feels like" temperature which takes into account wind ect. And tonight it will get down to -45*F (-43* C) I've heard alot of stories, and a old post that discussed alums vs cast https://mustangsandmore.com/ubb/Forum12/HTML/004352.html ------------------

I think it is 75 deg. outside right now!
I have been working on my tan
I remember those old posts.
I think Aluminum heads are fine in less than arctic climates. Absolutely fine anywhere south of the Mason-Dixon line.

I think with good gaskets and care the aluminum heads are fine. BUT while being in a warm climate might help, you MUST NEVER let aluminum heads overheat. ONE time is enough to make them bend out of shape and need milling. I was discussing this with another member the other day. He pointed out that aftermarket heads also have the exhaust port crossover blocked (non exsistant) which also makes running in colder climates more difficult. I cant believe that the as cast topline heads will make as much power and torque as a CNC port head. The flow might be there at .500 inch lift but what about low lift flow, and variation between cylinders. CNC ports seem a more elegant solution to me. Every port is exactly the same. Maybe the topline heads are good but 1200 bucks assembled isnt much cheaper than AFR. TFS heads can be had for 1000 now.

For those scared of aluminum:at $800 www.powerheads.com can sell you some CNC ported 351W heads. They seem to make good power. Not as much as the magazines are claiming for AFR's though. ------------------

Why spend 800 on used heads when you can get heads that flow 40 more cfm on the intake for the same money? Shaver Racing Heads has the Pro Top Line Cast Iron for 630 bare. You can go all the way to the 215 cc head for the same price.

Dubz, are you planning on driving the torino in winter when the engine is done? If it is eventually only going to be a mainly summer time car I wouldnt worry about the alum. heads. I think I am kind of in the same boat as you with my Coug. & after I get my 392 built up I dont plan on driving it in the winter anymore therefore I am going with aluminum heads.

it for sure won't be a winter car, but late fall and spring we usually have big temerature changes over the course of a day, and i'd like to get as many driving days out of the car as possible

Well, now the question of "who makes the best performing (not just flowing)iron head?" pops up.World Products Windsor JR
World Products Roush 200
Pro Topline 180cc in iron
Pro Topline 200cc in iron
or the CNC ported 351W heads
or any other you guys can think of ------------------

tttanyone have any input, i heard rumors that afr helped design the pro toplines...or something along that lines, anyone know of anyone using the newer ford heads to know if they are worthwhile (since i live in Canada it's a bitch to send anything back if it's not good, or if anything is busted)

As a guess, I would say the Pro Topline in iron would be the best iron head.
You can find the old TFS High Ports in iron on ebay sometimes also. These old heads seem to be proven power makers.
I have not run any of these heads but here is what I would guess as good candidates.1. Pro Topline
2. Used TFS highports
3. SVO N-351 heads (requires special exhaust flange, and special, but not supoer expensive rocker arms)
4. lastly because of core shift and casting flash, Roush 200. I would not spend the money for cnc ported factory castings IMHO. A lot of guys like the N351 head. It has like a 10 degree valve angle (pistons made for this head have NO VALVE RELIEFS per JE)and you can use pretty much any piston I would guess, and a large exhaust port.
Well, now that I think about it more, any of the Topline, TFS and N351 should give good results. I would boil down to how the heads are ported/prepped I guess. [This message has been edited by Mpcoluv (edited 01-08-2004).]
