leaky heads gaskets, I'm losing it!

a brass wire wheel is much softer than cast iron. On Aluminum is a no-no. Get a piece of thick glass or a granite floor tile and glue a piece of 600 grit on its shiny face, nice and flat. Run this over the gasket plane a few times nice and easy and see if any area is getting missed, there is your low spot.

The success of an wire wheel on IRON deck surfaces, only if it's not razor scrapeable , is based mostly on the operator.
I can graze a IRON head with wheel and change nothing in regards to flatness.
It will destroy an ALUMINUM deck of course.

SIDE NOTE-Most people dont even need to mill their heads half as frequently as they do..
No one checks.. they just mill like it's a sbc with raised blhead bolt holes.
Sbc is crap, thin sliced crap.
