Cleaning head and 'new' camshaft sprockets

Hi Folks,

Did a little more cleaning on the head and installed 'new' camshaft sprockets.  Spent a bit of time on the phone and email to get a feel for what the maximum warpage allowed without having to skim the mating surfaces and thus far haven't been able to find any firm answers.  My inclination is to avoid the hazards of getting it machined and use a Cometic brand head gasket which is supposed to be superior to the OEM gasket, but this approach  may not seal and I'll be redoing the head with it in the car.  I think Jennifer is going to have to help me with this decision.
My version of a 'leak down' test-passed with flying colors

Looking good enough to install?

Better cam sprocket design with finer serration's and solid plate 

New vs Old, The old version is thought to be weaker than the one on the left  and should be a good improvement


Tomorrow will need to prepare an order for SNG and make a decision on skim vs non skim.

Cheers,
Lynn
