Breathing new life into the 318 in the Scamp!
2nd thought;
These are right about what I'd be looking for in comp height and leave me with .067" -

but I'm almost positive that they would need balanced.
That set would land 8.96:1, which I could live with and I would still have the piston to valve clearance that I needed.
So... Do I juggle $50-75 between the higher cost of a set of KB's or get magnum pistons and spend the coin on balancing? It almost seems like it would make the engine run better if I got the late pistons, lighten up reciprocating weight, lighten up rotating weight and make it run smoother, but I can see benefit for a better quench, I'd almost have to mess with cc to blend the heads with KB's on pump gas.

Those would put it at 9.56:1... I don't know if going that high in comp ratio would be the right move? I could mod the head with some blending on the close/ heart shape side for flame and it would go slightly higher cc in head, but would it be more beneficial than the magnum piston + balancing?
IRL, the cc may be even higher in the head. I won't know until I get some plastic this week. if I blend it for flame propagation, it will go even higher, drop compression from 9.56 and help keep it from detonation.
I'm just wondering if a 9.5 ish CR is too much?
