looking for suggestions

I have a fresh .040 over chevy 350 (factory roller motor), stock internals, KB 3418 (-5cc valve relief flattop) pistons .020 in the hole and some Mr Gasket (.028 compressed) head gaskets (~.048 quench). Due to unforseen circumstances I am considering buying new heads for this motor (orig. plan was to re-use my 882's for approx. 9:1 CR). I would like to use a 64cc aluminum head (edelbrock or similar with <190cc intake runner) but am concerned about the compression (approx 10.2:1 w/64cc) and cam selection.
I don't want to turn the motor past 5500 rpm so will be using a fairly small cam and I want it to run on 89 octane for daily use. Is this doable or should I look at some 72cc chamber heads?

I dont think 10.2-1 with 89 octane will be very friendly. Id look for the 72cc heads. Hg

To me since you are going to keep it at low rpms why not use the stock 9 to 1 heads. Put the money somewhere else. ricco

10.2 - 10.3 CR with aluminum heads and .039 quench on 89 octane with no problems. Timing is 37* all in by 2600 rpm.

Glen242, Please explain your reference to .039 quench. What does this mean?
Thanks.
