Shaved Heads
Hey all,
When I had my new to me tpi heads in at the machine shop they said they ported and polished them and then shaved them. Exactly what do they mean by shaving them and what does that do to my car?

They milled the deck surface of the heads, to clean them up. It will raise the compression depending upon how much they milled.
