Vortec head question

[Dr.Gixxer]

I have the option of 2 different sets of heads and was wondering if either of them were any better then the other.

Casting #'s are
10235772
and
12557113
Any help appreciated.

The major difference is between trhe early head 96-00 and 01+ is the shaft mounted rockers. If you going to run shaft mount rocker then it makes a difference. If your going ot drill them out for common SBC rocker stud, then it doesn't matter.

if you are not going for a all out over the top build I'd go shaft mount. very cool setup and I like to no adjustment thing. keeps the kiss factor high IMO.

Re: Vortec head question

A Vortec conversion with shaft rockers MAY require custom length pushrods to properly preload the lifters. This must be checked on assembly.

I have some 772s I was going to use, but wanted to use shaft mount rockers. I think the 772s came off of a 96. Does this mean I won't be able to use the shaft mounts on these heads?

The 772 have a 10mm stud. The shaft mount rocker use a 8mm bolt, so no you can't reasonably convert 772 to shaft mounted rockers.
