If you look at Leo Santucci's first book (second I think too) there is a photo of a lump port head done by Mike Kirby at Sissal's for a turbo application. I am pretty sure this head was originally built for Leo. I actually own that head (purchasded it used) although I have never used it. Epoxy lumps for turbo application.
