How much has everyone milled there A6 head with stock pistons and cam/valves. wanting to know how far I can go before I have to start worrying about a collision.

Don't take off more than .040

I have gone to 80k with ZERO issues. Also I run CRANE 14 Cam and P-29's

 

[transzex]

what plugs you running then?

I just did the basic setup. Take off .030", run a y8 head gasket and that ends up being 10:1

 

[BigTuna]

stock plugs, didnt matter 5 or 6 heat range

I took off .075. Buts its not going to be a streetable motor.

So this can be easily obtained without having to worry about valve piston contact? Stock cam and pistons for 10:1. Thanks guys for replies anybody else??

So, .030 and a Y8 gasket yields 10:1? What's the max you can take off before you have to worry about clearences? .070????? How bout for the belt slipping teeth?

shaved

there was a post on here or on sohchonda.com that showed the amount of timing retard that you got from shaving/milling. i think it was one degree for every 0.012 milled, which with every tooth being 8 degrees you'll need a cam gear to get timing back to tdc. and you can just tighten the tensioner if you need to compensate for the small amount slack in the timing belt.


if you read this before the edit, i forgot that when dropping an a6 cam in a b2/b7 that the cam is off 1/2 a tooth or 4 deg, not 2 deg like mine, but then mine was milled 0.024.

each tooth on the camgear on a single cam is like 11.75 degrees or something like that...

when you shave your head alot.. theres timing belt fitment issues to worry about

i've heard .60 at most with stock parts but reliability goes way down, personally i would say no more than .40 with stock parts

 

[daveb91]

So it looks like .030 milled and a .030 thick gasket will be safe?
