Default Milled 799 + cam

Yes, yes, I know... "MEASURE!!11!!!!ONEONEONE!!!!"

Ok, great advise! I'd just like to possibly know ahead of time instead of being surprised.

Do you guys think I would have PTV issues with stock 799 heads milled 0.015-0.020 with a 228/232 .588 .595 110+2? Stock gaskets, rocker arms.

Probably be tight since your around the .230 mark but I doubt it. Now you check it and tell me what I win if no contact

If cam is cut correctly you'll have around .065>.07x clearance on intake. Tight but more clearance than some of the big cams around.

Hmm, I don't want to have to flycut my pistons. I'd probably just mill them .015, that should get it to 62cc, right? But crap, then I'd have milled heads and a tight clearance..

I think it would be somewhere around there.

It'll be fine cut .020, I do it all the time. Just run a good spring. PTV is slightly tight, but nothing to worry about. Having an A4, you don't have the worry of missing gears and mechanically over revving the engine.

I've ran intake clearance in the ~.040-.050 range before and been fine on my own stuff. Some of these magic stick, vindicator, etc cams are in the .040 range on stock heads.

That is about as tight as ive seen too. You will be fine.
