head gasket

To put '91 350 heads on a '87 305, which head gaskets do I use? Thanks.

any gasket for a small block chevy. to determine the gasket thickness youll have to crunch the numbers. I need to know the dish of your pistons, and the size of your compression chambers on the 350 heads.

but if you dont mind my asking, why are you installing 350 heads on a 305? its usually counter productive.
