My old 383 -66 bottom end is worn out and I’ve got my hands on an rebuild .030 bottom end with new bearings and Sealed Power/Speed Pro L2315NF30 forged piston.

I’m planning to move all the stuff from the worn out bottom end to the rebuild bottom end.
The camshaft I’m using is a mild Lunati:
Advertised Duration (Int/Exh): 256/262
Duration @ .050 (Int/Exh): 213/220
Gross Valve Lift (Int/Exh): .454/.475
LSA/ICL: 112/108

Do you think I can use my renovated 915 heads or would 9.77 CR be too much for pump gas?

Any thoughts on what HP I can expect?
 
Let's start with C.C. ing the heads first.( You Tube has several threads here . Myself personally : Start with a zero decked block ,and head c.c. and head gaskets "establish quench ". There is a sweet spot ,where detonation , goes away. It's called "quench" ...and probably the key ingredient, to pump gas horsepower. This is set in stone on normally aspirated engines, carburetor style. (In my opinion )
Others ,will chime in.
 
Well, measured the 915 heads to a tiny little less than 8cl which should be about 80 CC, zero decked block and MrGasket 040 head gaskets.
Eddie 600cfm carb, dual plane Mopar M1 alu intake, HP manifolds with dual 2.5" exhaust.
What HP do you think I can expect with the CR and cam shaft above?
