In short, if you go aluminum don't dabble with the gt40x, if you're in low budget mode, stay with cast iron gt40 (p) heads
Well maybe not the AFR's But def can find the tfs 170cc heads in that price range. Especially with the release of the new 11r head design. Fwiw not knocking gt40 guys. I'd just spend the extra for alum headsIf you find any more AFR 165's for $500.00 let me know. Meanwhile I prefer the GT40 over the GT40P only for personal preferences such as ease of spark plug replacement and lack of burned boots. I also like the fact they have no thermactor ports and larger valves.
Oh I wholeheartedly agree. I'd prefer aluminum. I just hadn't seen any real deals that I could put my hands on and look at before a purchase. I'd have to buy them local. And "P" heads have some good features. I'm just too old to jack with some of the issues.Well maybe not the AFR's But def can find the tfs 170cc heads in that price range.

Care to elaborate? Curious as to your theory behind this. (PS I don't want to start a Doritos Taco Food Fight, just curious)They also will handle the heat of the supercharger better

I'm picking up what you're putting down! Thanks. I didn't want someone to misconstrue that statement.Sure. Iron heads do not dissipate the heat as fast as alum heads and keep it in the cylinder longer. Alum heads don't dissipate the heat as fast, but also tend to not warp as fast as alum heads to to overheating. Now that has nothing to do with the amount of hp the heads will make, or the amount of timing you can run the heads at. Simply talking about the heat levels.
AFR heads can be had cheap. I'm in the process of selling the pair off my car (local to me, already spoken for) for $650.00. Can I get more for them perhaps? Personally, I want a no haggle price to get rid of them. Needless to say, they are out there.
Yes sir, good enough for me to go mid 11s. But deals are out there, just got to find them. I'm selling mine fully assembled.165's? They are a decent entry level head. Personally I would rather get the TW170's. Bigger valves, so much more room to grow. However, for $650, if those heads are not beat up,thats a good price.
Well boys it looks like the head gasket really is blown. I will know for sure tomorrow. Where can I get a set of these GT 40 heads for $250? What will I need to do to them?
I can't find 42lb injectors. Either 34lb, 39lb, and 47lb injectors. Also, that 90MM MAF is for a 2001-2004. Is that going to even work for my 89?
Oh, I don't know about that. I've got a set of GT40X's on my 331 and am quite happy with them. Car pulls strong all the way to red line and the heads are about as direct bolt on as you're going to get. Not the performers that the Trick Flows or AFR's are, but still comparable...and still a step above the GT40/ GT40p's.In short, if you go aluminum don't dabble with the gt40x, if you're in low budget mode, stay with cast iron gt40 (p) heads
