if you have your power valves ceramic coated , they are damn near self cleaning.....

sent them out for 3 customers now and they seem to be glad they had it done......

they havent been back , so.........time will tell

(i didnt suggest that be done , the customer did, and after knowing they do coat the pistons , i said OK)

i would think that the polymoly coating would be better for power valves, no?

i have no idea,i dont have valves in my 9 , so i really do not know
im waiting to see these valves this spring......

the polymoly is designed specifically for the conditions a powervalve would see. might want to look into it for future customers.
i've been considering having mine done for awhile now, just havent gotten around to it.

what i know of as far as the poly moly , 2 friends had thier chains and gears coated, i dont ask many questions from customers, but i can see why........

i usually have the piston skirts done with polymoly while i'm having the domes ceramic coated. it is very thing so it adds nothing to the clearances but it definitely works.
