Which heads for my 383 SBC? I am building a 383 SBC. I am filling it with an Eagle steel crank, Scat rods, JE or Diamond pistons, a Comp XR286R-10 camshaft and a Victor Jr. intake and a 850 double pumper. This is all going to be stuffed in a full weight 68 Camaro. This motor is also going to be subject to a 150+ shot of nitrous.
BUT I have to decide which heads to run!

Re: Which heads for my 383 SBC? GM's 23-Degree Aluminum Fast Burns (210cc) seem to be very popular. Though I hear the Motown and AFR heads can put out some serious numbers...
I'd say go with the AFR units if you're looking for a lower CR.

Re: Which heads for my 383 SBC? According to Desktop Dyno2000 the AFR's and the Canfeilds made the most power. The only heads that made more power were the GM 15 and 18 degree heads. The AFR's put out around 538 hp @ 6500 rpm and the Canfeilds put out like 534 @ 6500 also. This was with large tube headers with mufflers... I'm not sure what sizeit means when it says "large tube" but I'm guess a hooker super comp would fall under that category.

Re: Which heads for my 383 SBC? TTT. Gunna go look around Friday and check on some prices and stuff.(not too worried about prices so go by what you think is the best head)<--its not like I want to spend 2K on a set of heads that I probably won't use but one time though.

Re: Which heads for my 383 SBC? Ever heard of Pro Action Iron lightning? They would be my choice if I were gonna use iron heads. But for aluminum, you can't beat the price and the performance of the canfield's.

Re: Which heads for my 383 SBC? Trick flow chevy heads from TEA. The others are ok. But for ultimate power get the 18 deg trick flows. 380 cfm intake and 280 ex with very minimal work.
