Hi tlowe, Thanks for the reply.
Its quite hard to read in the photo but looks like its 3838021.
Reason im asking is i have 250ci chevy here in New Zealand. But believe it or not, they are quite thin on the ground here and I have a cracked head.
I have found a pontiac head in the USA and wondered if it would give me similar benefits to a 194 head.
Cheers Craig
