Cool,
I'd definitely like to see the jig and setup.
I haven't found jack on Edelbrock pistons.

Woops,

any advice would be great .
As long as these pistons are forged and not cast, you should be able to customize them. How much? measure twice and cut once.

measure the skirts, pistons are not always round which could be an issue chucking it up.

very true for what most will encounter. but there are round pistons like the old trunk pistons with upper and lower rings. there are even cameo cooky shaped pistons.
