I'm in the process of rebuilding my 327 it's a standard 327 with flat pistons with 4 recesses for the valves, I bought a new camshaft for it : http://www.compcams.com/Company/CC/c...x?csid=80&sb=2
and have upgraded to Lunati roller rockers with 1.5 standard ratio
But now when I have pressure on the lifters and try to spin it it hits the pistons on the exhaust valve...
I have comp cams timing chain and if I advance the cam with 4 degree's could that solve the problem?
