I found an experienced and very reputable head porter who will do a three angle valve job on my head with his SERDI machine. This is the only head service I really want.
His specialty is honda car engines so I think I'll have him leave the ports alone and just clean up around the valve pockets a little.
My question is about port matching. Should I have him match the exhaust ports to my White Brothers header?
What do you think?
