    whats up? A friend of mine was telling me that you can raise the compression of a motor without effecting the crank, rods, head gasket, or pistons; he said it's something much easier then changing these parts. He works for a shop, and he said it was a trade sercet. Do you know what his shop is doing? He wont tell me...

    he is probly talking about plaining the head (removing material from the head)

    this really isnt the "best" way to get higher compression and may lead to larger problems if not done correctly and kept within spec

    yup same shit .... all just different ways of saying that you are removing material in hopes of higher compression


    valve clearances can get sketchy doing this though

    Maybe he's just waiting for the pistons to get really crusty and carbon coated after 100k miles... that will get you some more compression right there. Larger domes, here we come!

    why in the hell would he talk about not changing the head gasket? ...its a hell of a lot easier than milling the head.

    MAGIC!!!

    don't mill your head to rainse compression, milling is primarily used to flatten the head out after warping or improper fittament to the block.
