So I’ve got a 2007 mercruiser v6 I know a swear word for Chevy. I need new heads for it. I can find the casting numbers online but there’s a few numbers that don’t match up with mine and I’m in need of expert advice as to what I need because I’m only wanting to buy the right ones. Any help much appreciated!!

 

Welcome to the forum. You might try to contact the Mercruiser factory in Oklahoma to see if they can help you or check with a Chevy parts department because they should still carry those in there database.
