i dont know about the port an polish tbh... dnt think so the head looked like it had been skimmed a few times too many tho

ive had to move the dizzy to get it to run tidy enough to drive because when i first started it, it run like a pig so tryed movin dizzy then re-checked the timing marks (spot on standard marks) also i broke my T peice to the boost gauge so cant tell wat its boostin till i get a new one tomorrow im going to check the emissions an maybe turn the boost down on the actuator as it seems to be tryin to boost more than before.

a thought do you think it could be blowin the spark out once boost pressure gets to high?
