Removing valve seats Anyone know how in the hell I can get these things out without taking it to a machine shop to have them cut out? Is it possible to pry them out with something? I am about to fly cut the pistons but can't get the damn things out, so any help would be great.
If the head is junk and you dont plan on using it again, you can just slot the valve seats with a dremel or angle grinder. Once you slot them, it relieves pressure and you can pry them out with a screwdriver.

This may be another stupid question, but why do they have to come out anyway? The tool cutter shaft fits through it. Doe it not let it get close enough to the piston?
I took my die grinder with a .080 thick metal cutting disk and vertically cut down the wall between the intake and exhaust valve seats. This will cut through both valve seats and the aluminum between teh two valves per cylinder. Wont matter if youre just using the head for flycutting.

Verdad Gallardo Dont worry, you wont screw it up unless you spend your days banging into walls with a helmet and licking windows on the back of the short bus. Its very easy to do, but a little time consuming and possibly frustrating trying to get the angle drill in tight spaces.

This will work very well. It is pretty straight forward and easy to do.

Just finished it now actually. It was very easy to do. Now time to go cut the pistons and bolt on the AFR's!
