Got delivery of Scotts head today
Its been stripped and inspected, going in for x-ray tomorrow to make sure there isn't any cracks, They don't normally get cracked but its alway good to make sure
Standard ports
Big gouge in the head face but i'm sure it will skim out
Mine are a copy of a CNC heads by Rick woods as I bought a damaged one cheap from someone for a friend for bench mark for myself. It's been tested by a friend that borrow a flow bench from and it's the same as a CNC heads head. I don't keep the test results myself as it's just a tool to make...
I always finish of the ports with a 60 grit for the inlet and 80 grit for exhaust.
no polishing at all. No gains and no point.
All guides are de burred and cleaned up after.
