head casting numbers.....

so im looking for heads for my 400 and i emailed this guy and he tells me that he has "I have a pair of 1970 # 13's $350, a pair of # 96's $450, a pair of # 4X's or # 6X's $200 all are bolt on's" i tried looking up these heads and have no idea what they are so if you guys could help me that would be great.

Thanks, Ryan

Re: head casting numbers.....

Those sound like Pontiac castings. I'm quite sure the 4X & 6X are.

Pontiac heads won't fit a Chevy motor. They are COMPLETELY different in every way.
