Help me identify these heads
I'm trying to find out what aluminum cylinder heads I have on my GM 350 crate engine. No casting markings or logo on the ends of the heads.
I did find the following part number on the exhaust manifold mounting surface between the two center ports. XPC 3002-2018-05-22-0570 The only thing I've been able to find is is a part number PC-3002 for Speedmaster heads. |

Re: Help me identify these heads
Pro-Comp Speedmaster 190's, 64cc chambers. They're a generic mass produced SBC aluminum head made in China...
