23 DEGREE HEADS
I know that there is 18 and 15 degrees for race engines, but i was trying to find out what a 350 block is and does the diffrent degrees come in on the intake side or the block side. I have a set of patriot heads on a 383 with a air gap rpm intake is this 23 deg. or something else. Has anyone used the patriot heads with 2.05 intake and 1.96 exhaust just wondering if they were any good.
