They sit way down in the hole as SOP and the additional valve reliefs add a bunch of extra chamber cc's,so understand that those pistons offer absolultey nothing desireable.
There are tons of posts here about those POS cast 8 relief pistons,a search will bring plenty of that info up.
Just go .030" over,that .010" over bore difference is NBD @ all,and for sure use a forged piston,and yeah get a set of the "budget" aftermarket forged rods too.
You'll be glad you did.
I would probably recommend the KB/Icon #KB891 forged pistons myself.
I'd also highly recommend zero decking the combo with ^^^^ those pistons too.
Those #13 heads will likely end up around 76 to 78 cc or so w/o milling them.
But I'd CC those #13 heads just to be 100% sure where I stood in the CR department.
FWIW

Listen to Bret....he's absolutely right. Those 8 relief pcs. of junk are good for ashtrays and paperweights, and that's about all.
