yes, thanks Ian. pittsburghracer called vic at wiseco and set up a conversation for me with vic. turns out the shelf dome piston will work with the indy head, but the valve relief might not be quite big enough for a 2.100 intake valve and the 1.460 pin height may poke the piston out of the bore and vic says to keep piston below deck or 0 deck at most. I'm sold on the wiseco dome, so I think I may just do the custom piston thru flatlander. thanks pittsburghracer.
