I was looking at getting a Forged Bottom End.. 347ci... my question was.. Are all LS1 Rings already sized??.. the rings i found for the JE pistons on summit say.. File Fit: NO.. and i couldnt find if the Diamond Piston rings are file fit.. does any one know or is it better just to put the sized ones on..

I have ROSS pistons &ring in my 347cid. and i had to file to fit. And i had Diamond pistons in my stock cube motor and they had file to fit in them too. Diamond & Ross both told me they dont make fitted rings for there pistons .
