Go with AFR cylinder heads and don't look back !!!!
so what is the benefit with going AFR heads? bigger stickers? I am sure the company is reputable but the statement go with AFR and don't look back is not good advise. At min call them and go over your setup. Keep in mind if you rework your heads with the larger 2.10 vs the 2.05 valves you will need to open up the bowls. as far as i know the 1.60 exhaust valve is the max "no room to open them up more"
These should wake it up a bit too.
Well, they are very nice heads and have good flow #'s, sized right for the CI/application of course. Like anything, they can be improved upon.
But I will say, they have had their issues, not to mention the plastic intakes...one distributor close to me will NOT sell anymore AFR heads!!!
Funny how the big flow #'s don't necessarily correlate to the dyno/actual track performance in all cases. Shape, valve train position and core stability, not to mention material is tops on my list of importance, even if the flow #'s are low. Dart and Brodix are good top brands to look at also.
First and foremost, what kind of budget are you working with?
$1000-2000 I guess.
is there a reason you have to have aluminum?
No, never specified they had to be aluminum. Just want to find a good set of heads to compliment my cam and other existing parts
I have Dart SHP 180 aluminum heads which I milled to 62cc. I bought them complete with dial springs. Very pleased with quality and durability at 9K miles so far. They are on an original 72 Z28 block that is .030 over with forged flat top Wiseco pistons, original pink rods and 1182 forged crank, std/std, melling high volume pump, original LT-1 oil pan and windage tray, Holley Street Dominator 300-36 intake, Holley 780 3310-2 carb, MSD Pro Billet distributor and Lunati 107120703 cam. Runs quite well. If I remember correctly the heads were $1,000.
I'm very happy with my AFR 210 heads on my new motor , throttle response is very responsive
