thats the question?

also whats the deal with a 5 angle valve job?

what about changing the valves, guides, retainers, and springs? do changing these things fail emissions?

i know that cams wont pass emissions, correct?

haow about the accufab, c&l, or dragon plenttums will they pass?

sorry about all the small Q. but i really don't want to jepordize emissions to much, no telling what the future will hold for that. and i really want to speed up the car.

i dont think it would, besides it not like they will take the time to pull off your valve covers and check

I don't think you'd have a problem with p&p'd heads.

well i usually just pay money for a sticker at certin places, but you never know what happens with emission laws. they might revoke all those smaller emission testers licences in a couple of years and force everyone to go through the dmv. that would suck. so im just trying to keep my car fairly legal. i would like cams but can skip them, but i want to do the heads and plentium.

I was told by someone from Power Heads that anything that is factory will pass emissions, even if you port and polish it. Cams can be a problem, but as long as what you get is a stock part from Ford, such as PI heads or whatever, you'll be fine.
