232/236 cam ok with these heads? I have a set of 5.7 heads that were milled .030. They have a 2.02/1.55(whatever stock size is stock size) SS valves and were ported etc...
My cam is an XE-R 232/236 .585/.585 113lsa set on 0 degrees of advance. My question is will this cam be to big for the motor since I am on a stock shortblock with NO flycutting?
I will not flycut the pistons so that is out of the question. I keep hearing conflicting advise on yes and no from many people. Any help would be great!
I will be useing the crane duals to avoid floating.
Thanx! ~Eddie

I'll just put it this way. My roomate just bought a set of patriots LS6 style castings that were barely milled at all. They mocked up the motor with the F13 cam (230/232 .591/.581 112) and the clearance was too close for comfort.

Guys you could go back and forth on this for years to come.
1- degree the cam
2- Clay to get a clearer picture (both intake and exhaust)
3- The best way is to use a dial indicator (in general clay readings are .02 off (+) than dial readings.)
IMO I wouldn't go with less than a .10 int & .12 exht clearance on any cam. These are street engines, not track only.
Some will tell you I'm running .08 etc... untill the day. If a spring brakes, (even a double) the valve will sag a little, but this is up to you.

It was a black 00' SS M6. 
I flycut the pistons .060", and had approx. .125" of clearance. This was with a 2.055 int and 1.60 exh valve.
The cam was a Comp 232/236 .580/.580 on a 110 LSA, and 108 ICL. I had Comp grind it on thier Renegade lobes, which are the lobes the NMRA Renegade class racers use......needless to say it was pretty frickin nasty!
