Is diamond cutting the heads and jugs really worth 600.00 plus the down time ( remember down here there is no down time) weather wise here? It has always been my belief ( If it doesn't make it go faster or make it stop quicker ) then it's not worth the bucks!!

Thanks

 

seems to me you have made up your mind already, supposedly runs cooler but, i did it while my motor was down for crank work, and i did purely for cosmetic.
