If you are going to have the head off for a p&p, you should have them do a 3 or 5 angle valve job also. You might also want to have them mill the head. That's where the machine shop grinds a little off of the bottom of the head (side that mates with the block) - that's an old-school way of increasing the comp. ratio (more power captain). That's also one of the ways 900S got the "meatball" to it's power level.

--note: there is math involved in the milling process; so read up on it, or let the machine shop do it and guarantee their work. A good book to read on this stuff it "auto math" you can get it online at amazon (so you can see a sample), or most big book stores. --
