Is this something you sell? If so what quantity can it be obtained?
Thanks.

What about in a race engine? Thanks!!

(Like texture left with an course aluminum burr) And what about immediatly below the valve job in the bowl area?

Can you suggest mainstream way to prep cylinders for new non-chrome rings. Liners in good shape no scratches. Diamond rough up hone?

I have tried putting a radius on the OD of the exhaust valve head (combustion chamber side of valve) to help the exhaust gases get around the valve head more easily. But so far I always loose flow on the flow bench with this modification. My testing has been with 70’s era OEM GM cast iron heads.

What are your thoughts and experiences with this?
Thanks!
