Head Gasket Question

[MaxFarmer]

The only thing I could find to add right now from my scribbles is that a compressed A gasket is supposed to be .035-.039 inches and a C gasket is supposed to be .039-.043 inches.
That doesnt sound right though b/c I dont know where the B should be in there. Maybe something in between?

How much is a head gasket set from the dealer?

 

[Lonnie]

Depending on the discount you can work with your dealer, gaskets are approx $90-110 each side. Took me almost 2 weeks to get one from GM.
Bolts are about $40-50/side.
Copper injector washers (LLY) about $2.25 each.
Injector o-rings (LLY) about $8 ea. (ripoff considering a normal o-ring costs about $0.75)
Lower valve cover gasket (LLY) is $80 (be careful when you remove yours as it can be reused).
Upper gasket can be reused as well.

Thank you Lonnie. You just answered my question about the valve cover gaskets.
