Looking for info on LS7 heads. Heading to a friends house to look at a pair of supposedly LS7 heads mounted on an LS6 motor. I looked thru my Colvins but couldn't find info on these heads. My understanding was that, although there is folklore saying that LS7 motors made it into production cars, these were only available OTC.

Questions:

1. Cylinder Head Casting #?
2. Correct date range for heads (how long were they available)?
3. What are the external identifying features/marks i.e. casting flash line feature
4. Composition: Iron or Aluminum?

Any other pertinent info to ID these heads.

Thanks,
Sam
