Hi Bud Good to hear from you yesterday took more parts in to be coated,I should have them back in 2 weeks.I'll post some pics of them whem I get them.The coating is defintely best for both WC-1 and NE cylinder,even if only doing the piston .I got my whizzer from new in 1999 and have had a chance to see all the different things done to help fix the problems.we where having,oil purging,valve seats lifting,milling head and then it gets a hair line crack near spark plug hole with 14mm plug heads.Don't forget to advance your timing 1 tooth WC-1 or NE and set your lifters at .009 exhaust and .007 intake for the WC-1. .006 intake and.008 exhaust for HP cams.When we first got our HP cams they didn't come with mushroom lifters,we used caseharden lifters,whizzer didn't use them and the lifters mushroom them self.I have some of the casharden lifters if you want them I can give them to you.Any ways I think its always good to give it to fresh eyes,their are 7 thousand of us out there with the same questions.Ray
