so you have drilled them for steam holes

 

Yes they were dilled by AFR. They can still be used on a 350 or 400 bring the gasket for the 350 will cover those holes or if a 400 the gasket will have the holes.

 

Sent you a pm.

 

Sorry guys but because of lack of interest I posted these on Ebay. Figured with no real interest here in 2 weeks.
