13:1 Compression Pistons in 340 Small Block

I would go with a set of flat tops for your intended use. With stock port J heads I would keep the max lift to around .500” or so.

So if I wanted to run these pistons what type of lift for a cam are we talking? I’m probably gonna port the head I have or the ones I pulled I think are already ported I’ll have to check.
