Cam advice for ill advised 318 combo?

Real quick, on the j heads, cc them...cause new valves sitting on a bigger seat 'sitting proud' can reduce the chamber volume quite a bit and you may find out that the chamber a lot smaller than any of us can assume. Last set of 72 cc 1.88 heads I did ended up a 62 cc's after installing 2.02/1.60 valves and a .010 mill, valves sit proud on a fresh seat that hasn't been cut a dozen times.
