Question very dumb porting question

are you able to port the exhaust slightly without tearing the motor apart and causing a rebuild? my 12a only has 10k on it. but i want a lil more exhaust flow.

Nope. Theoretically you could, but you will still need to add a bevel.

Not off hand. Ditch the points and go to electronic, 80-85.

Do a search on how to swap it over. Runs better and no more feeler gauges
