Nascar Engine question

[makovai]

The old Nascars had the 4.3 liter aluminum engines. My boss has a new one. He needs info on the this setup he's building and no-one can seem to get specs on the heads. He needs valve lengths, angles etc......

The heads say pontiac # 10045448 on 1 and 10045449 on the other.

Does anybody know any info on these heads or know where to get the info?



Thanks

(this latter is a long page, search for "10045449" on it.)
