I am building a 342. 302 block std bore, 5140 forged crank w/3.40 stroke, 5.315 rods, probe 1.175 pistons w/14.2cc dish, 302 Edelbrock Victor JR intake. Haven't determined cam yet.
Heads I have are stock 302 58.2cc heads 1.78/1.45 valves gasket matched/light porting ( smothened out and smog bumps removed ). Still have press in rocker studs but will upgrade to screw in's. CR figures out to 9.73:1 with this set up.
Question is will the stock 302 heads with the light porting still allow the 347 to perform well? I know the gt40P's would be a better choice and plan to upgrade to them later ( budget right now won't allow it ).
Also will the 302 Victor JR intake work with the GT40P heads when I do get to upgrade?
