Old topic, but very interestign one, so, i have a 420 sb x-block stroker, 4.125"molnar crank, with molnar chevy rods, ross pistons 11:1/63cc. And thinking to go with indy 360-1, but are these 245cnc 2.14"/1.65" heads too big for me. street/strip car and i can get that cr up to 11.5:1.(pump gas) I go with solid roller cam (it will be custom one). How about that 2.14 intake, is it too close to touch cylinder, i have a small bore 4.03".
I'm running Raised port versions of the 360-1 cnc 245 heads, they have 2.100"/1.625 valves and while close they clear 4.030 bore.
