Maximum to shave off the head

ianstaley · 06-22-2013, 10:27 AM

Ah okay, thought you were going turbo sorry. I think that taking a few though shouldn't be a problem , however, there is always one isn't there, the MK3 is a non interference engine but I am thinking that take too much off it could become an interference engine, make sure the company that is doing the shaving can tell you if the valves will interfere, hit the pistons, just incase the timing belt breaks.

Coming from Ian, I'd take this as gospel: "20 thousandths" So you'd be effectively doubling the height the piston crown extends past the deck in a clean, stock engine. Then you will want to account for it with your head gasket selection.

The only problem is that Ive already had the gasket for a while and it's a 1.4mm. Will that still work ok without running into any problems?
