Three of the bolts holding the Jesel stand go into original holes, four other bolts are new locations. The existing bolt holes get drilled and re-tapped to 7/16 thread instead of 3/8 thread. But, the original holes barely clean up.

Bottom line is that if you're going to run the Jesel set up it is better to start with a bare head that is machined that way rather than convert. The conversion can be done but I'd think for a full on race motor it would be better to start off the right way. I don't think Indy offers the EZ head with a Jesel option though but I suppose a person could arrange for a semi-custom setup.

The water pump is from Meziere. It is a bolt on reverse flow water pump so you don't have to use the Indy manifold thing.
