Valve cover adapter really needed?
I want to use the early perimeter bolt style valve on my ZZ383 instead of the center bolt that the fast burn heads use. I see that Trick Flow sells an adapter to allow this change. $ 100.00 +
Is this adapter really needed? It looks like if you use a thick stiff rubber type gasket and studs that are long enough that the adapter would not be needed.
Anyone using the early valve cover on the newer heads without an adapter?
