Engine rebuild info

[Hugh Mongus]

I am getting my engine rebuilt by a local shop. The rebuild is going to cost me $900. The mechanic said I could buy, and bring him, the cam I want to use with the engine and he will install it at no extra charge. I just ordered the Lunati 10602 kit that includes lifters, springs, retainers, and timing set. What compression ratio should I be shooting for to get the maximum performance out of this setup? What do I need to do to get that CR?

What I know about my engine:
4 bolt main
492 heads, 64cc, 2.02/1.60
Performer RPM intake
Performer 600cfm carb
Accel HEI ignition
Flowtech 1.5" tube full length headers

TH350
3:73 gears

I'm looking for low - mid range torque. I don't see much need for 600+ rpms since I will be driving this on the street and not at the strip.

What should I be asking the mechanic prior to the rebuild to make sure it will be a quality job? I haven't ever rebuilt an engine. I have always bought crate engines in the past.

Thanks in advance.
