.050 is fine, there is no real maximum... unless the lifter's punched right out of the case and is lying on the floor. Smiley

Cheers, gents!
We had already begun assembling the motor when I decided to check it out, and it's a good thing we did. After a LOT of lifter shuffling we got the 3-4 case half to nearly acceptable figures, .049" to .064". Both intakes were tighter than the exhausts(?). Decided to check on the 1-2 half and came up with very different numbers... After even more shuffling, the best numbers we could come up with was #2 intake and exhausts are a close .048"-.053", but the #1's are a tight .029"-.034" Sad

What would you do? (what I want to hear is that we can have a little taken off the tops of the #1 lifter bores and call it a day Wink)

Thanks!

That would be fine and dandy. As Richie says, anything is enough, but I prefer to allow around 40thou, although there isn't really any reason why! For peace of mind, mill #1 and have done with it... Smiley

that's what you need to do. Berg sells a cutter you can run in a drill press or even a hand drill if you're careful.
Most high perf lifters are already thinner on head. Are you guys using stock VW lifters or Mahles or something?
