Re: Spark Plug Protrusion into Head?
Hi Anthony, no good, needs to be addressed?
This has been an ongoing issue with ALL the different vendors with the aluminum heads. Some call for .437" reach, others .750", we find them all over the place?
How long is that plug from the gasket surface to the very first thread??
Thanks, Gary in N.Y.
P.S. This has been an ongoing issue with many of the aftermarket alum heads! We actually make our own "spacers" (photo below) to correct the plug depths!
