I am building a 69 Cutlass. I have a 5.3 motor out of an 03 Suburban. I have a set of 243 heads from my buddies vette motor (rod through block) to swap on the motor (along with the intake and injectors). My question is, What head gaskets do I need? The truck or the vette ones?

Should be the same!

Thanks. Thats what I assumed but wanted to make sure before I bought them.

Match them to what is bigger so in this case the heads. Get them for a 5.7

I've had good luck with the GM MLS .051" ones.
