and the C4AE-Gs have been angle milled a degree and a CNC LS7 port ground in as best as they can fit. The stock mirroring of the ports requires some creativity, LOL. Iron is also very hard on bits, they were done in 2002, have had the face milled to fit a street Dominator and is 10.25:1. 2.055-1.58 valves, it has a very lively quiet port, and does 274 intake at my cam lift and about 285 at .600 with 185-190 on the exhausts at cam lift and .600. it never pings with the L2291s and revs really quick to 6500-7000. I want to do better on my BBMs and build a 410.
