A search for "cylinder heads" didnt find you anything? Heads and camshafts are talked about daily on this forum.

Try Trick Flow 23 degree heads.

Try AFR, Trickflow.

There are tons of other choices out there.

Match your cam to the heads.

do some searching on other combos similar to yours and go from there.

a lot of aftermarket heads dont fit because of oversized egr or oversized coolant passages....

U dont have anything special, so search around here for the other 1000 people who have converted LT1 intakes on their car and look at what they are using for heads.
