i saw these lil sand paper flap wheel things at napa and was wondering if 80 grit would do it easier than the lil drums.

carbide cutting tips ordered, ordered 5 of the sand flapper thinggies just in case, they were a buck a piece, 1 inch in diameter.

 

i use them to polish, not metal removal. they work good i na die grinder.

 

yea i was planning on using the carbide tips to clean up the valve guides and gasket match, the just polish everything.....will i need to use the carbide tips to smooth out the combustion chamber/intake/exhaust ports. or can i just use the flaps.

 

i don't and wouldn't use the flaps in the chamber, i use 2" sanding disk and die grinder after carbide bits.

 

where do you use the flaps?? in the intake and exhaust ports?

what type of discs, ...flat?? drum type?? what grit?? sorry for all the questions, i just wanna do this right, and only once
