Cam specific questions OK guys I tried giving FMS a call to get some questions answered before my purchse but I get no response. I spent like 3 hours last night searching through posts to get some of my questions answered. I have decided to go with a FMS cam. My engine is an almost stock LS1 on a 2002 Pontiac Trans am with a 6-speed manual. The car will be a weekend car but I need it to be DD as well. I am undecided right now between the F13 and F14 but am leaning towards the F14 with the 114 LSA.
Does this cam require engine timing change?
I am also going with the FM2-Dual Upgrade-1 kit.
Do I need stronger lifters with this cam?
Will the stock rocker arms handle the cam?
My main concern are the heads. I do want to upgrade them but I can't afford $2000 for the AFR's.
What other more budget minded choices do I have for the heads?
Will milling the stock heads yield me reasonable performance gains or should I start with say 5.3 L heads and work on those?
What is the most I can do without having to worry about piston to valve clearance?
If you guys can give me a good idea on what exactly needs to be done to the heads to yeild the best gains without worrying about piston to valve clearance. I'd rather not have to get flycut pistons.
I'd apreciate if you guys could help me out.

Why don't you want to flycut? Will you be doing the install yourself? Flycutting isn't a very big deal once the heads are off anyway.
