Default L92 heads on LS1?

Can you use the L92 heads on a LS1 shortblock? I don't know if I want to switch over to a full L92 but was wondering if you can use these heads on the LS1, looks like they have great potential and great flow numers right out of the box.

-Found my answer now another question what would be the best combo with the L92 I am familiary with the LS1's but not the LS2's andL92 are they that much more intense as far as wiring and tuning? I'd like to stick with an LS1 but would like the full potential.

L92s will not work on an LS1, the 3.900 Bore is too small for the L92's 2.16" valve to fit.

You have to have a 6.0L block with a 4.00" bore minimum.

Hold your horses. They are not done yet.


And I don't have a firm date either.
