Difference between 6.2/6.5 heads? 60 or 90 degree?

[fullsizeBlazer]

Hi guys & experts:

I'm currently selling a set of NOS 6.2/ 6.5 (?) heads on ebay (Germany) to get money for the p400 engine I'd love to have.
Well, I got a email from a guy who wants to know if these heads would fit his 1996 GMC truck. he's looking for 90 degree (whatsoever) heads.

Hi
I belive the intake bolt holes are the ones that are diferent on the van heads.By looking at your pic's i would QUESS that your heads would work for the pickup engine.

If they are 6.2L, they are 90 degree.

What's the cast number? That'll tell you what it can work in, earlier 6.2 heads won't work well on a 6.5 (clearance issues with injectors and injector angle).
