Lee,

I'm not sure if you understood me from the get go. I don't have those lumps you are refering to. I have looked over Santucci's book and now I know what you mean by lump port for the exhuast. The book has a tremendous amount of PICTURES!!!!! Very cool book.

This head I have is for street use. Still has the intake boss but worked some. I worked the bosses on the exhaust too.

All the exhaust ports looked good 'cept #1 port. That bump took up A LOT of room so freeing it up like the other 5 exhuast ports I felt was neceassary...Take it easy hometown.

Almost done with the pictures crew.
