I have to pull the drivers side head, to remove a broke off sparkplug. My question is since i used the summt/sealedpower-speedpro kit how do i find out what head gasket that is ?? i belive its a felpro, although iam not sure on the thickness ?

Just curious, where is the spark plug "broke off" at to have to remove the head?

BTW, I would not go with Cometic, if you feel the need to run a MLS style gasket, go for the Fel-Pro version of them. I just ripped my pair off in disgust for seeping coolant out from between the layers (definitely not the first to experience this) and slapped some 1011-2's on there. I am sure the kit came with a fel-pro version head gasket equivalent to the OEM version picked up at the local auto store.

I really don't want to be having to pull both heads,. when i only have to pull one.
heck if iam going to do that i might aswell save up a few more weeks and buy some aftermarket heads or something better then e6s. Also do you have to shave heads every time you pull them??

No you don't have to "shave heads" every time you pull them. There is a tool out there called a machinist's straight edge that you lay across and diagonally in several spots on a surface. A feeler gauge is used and the thickest one is used to slide under the straight edge to determine the level of warpage. This determines if the surface must be re-machined flat (or shaved) or not. Or unless one just wants to bump compression up a bit.

E6 heads are on this thing?

Go to the local auto store and ask for a fel-pro replacement HG for your year engine.
