So I'm going to be decking my head about 6 thousands along with flat valves, springs, retainers blah blah blah. My question is, would using my brand new oem TCT be fine with the reduced head and OEM head gasket or should I upgrade to a Billman?

 

Get Billman's version and be done with it.

 

The OEM is so unreliable I don't know why you'd bother. Contact Billman and give him all of your specs, he'll set you up with one that will last the car's lifetime.

 

Go Billman. He machines down the mating face of the tct so it goes farther into the head, which allows it to keep more tension on the chain. This is a function you will need because the amount removed from decking the head results in slack in the chain.

 

Thanks guys I will contact Billman.
