While setting up to portmatch the manifolds i decided to get the dremel up in there to remove all the dags and rough casting marks.
Steering clear of altering the shape of the ports, concentrating on smoothing the surface. With the inlets i'm leaving a rougher texture and the exhuast ports (shown) im smoothing to a finer finish to limit carbon buildup. Under the watchful eye of experienced head builders i thought i'd have a crack.
What i started with.
This is a nearly finished exhuast port.
