Im glad to see a few flat tappet users out there having good results. I'm really not too worried about the amount of power loss with a flat tappet at this point as this will be 90% street driven. Just a pain to break in.
The roller worries would be with the valve spring and lift rebuilds. I used to have mine rebuilt every 3yrs which was about 2000miles and maybe 50 passes.
I dont think I said that I do use the Comp EDM lifters and as said i have had great results with no problems so far in the almost 5 years my eng has been together. Ron
