i also purchase a set of srp 8:5.1 pistons they are .0010 over.

No. You will have to take it to a local machine shop and have it bored and honed to your pistons. Since your running the SRP's you will more than likely have a low piston to wall clearance due to material they are made of. Hope this helps and good luck with your project

But do the SRP pistons he has have the p/w spec built in to them or not? I dunno, I wouldn't use those pistons personally but he's gonna have to look into that I suppose. Give their tech line a call, you will definetly want an accurate answer to your question or you will have serious problems later on down the road.

If you were'nt planning on boring out your sleeves, then just send the pistons back for stock 81mm pistons Also, I'm assuming the sleeves are honed, and ready to go?

Keep the pistons and bore the sleeves to get the correct clearance, or get new pistons for 81mm so you get the correct clearance without boring..
81mm pistons have the correct clearance build inn to be used in an exactly 81mm sleeve..

he said the Walls fill ruff so 81mm piston is not going to help him it will need to be bored and honed
