Couple other things:

Also note that if you want the heads finished, ie, removal of the CNC milling, that's an additional $300.

Also, those heads are set up for their cams, which are 550 lift. You're probably going with a bigger cam then that, then you need different springs, that and if they need to cut the heads for the springs, the price may go up a bit as well.

I had my heads done in 2000 by GTP, originally as stage IIs, When I decided to go faster I sent them back to have additioanl porting and larger exhaust valves. Haven't heard allot about him in recent years, not even sure his shop is still open? I did find this artical:

Honestly, I've compared on a bench my heads to a set of LEs and they are almost identical, Lyod appears to port a bit more on the roof of the track around the intake valve. Not sure how big a difference that might make in the flow numbers.

Interesting article ty...
