I would like some feedback from some of you more experienced head porters. I started this a few years ago, set it aside, and recently got back at it. I know a few things now that I didn't when I first started, and may have made a few mistakes that can't be undone.
1) I whittled the intake guide bosses down probably more than I should have. Do they look ok? Intake and exhausts are going to need guide inserts anyway. Can the guide insert hang past the guide boss this little bit, or do they have to sit flush?
2) I nicked one of the intake seats with my bit, and got too close to one of the exhaust seats. The exhaust seat doesn't have much sealing surface in the area where I got in too close. Will this require a trip to the machine shop to fix, will it seal alright as it is, or did I make a fancy door stop. Are exhaust seat inserts a viable option here?
I didn't see this until I did a light lap job. Probably should have done that FIRST so I could see them better and avoid hitting them.
If everything looks like it will check out and be feasible cost-wise, I plan on using these heads on a street engine. If I've ruined them, at least now I know a few things to do differently, and a few things NOT to do! This has been a great learning experience and kind of fun. Any tips and pointers will be graciously accepted. Thanks FABO friends!
