I'm sure I have read on here thats these camshafts are not the best I've had one in my car for a few years (hasn't even done 2k miles) and it made good power but developed a misfire the other day and I stripped it to find number 1,2,3 exhaust lobes heavily worn, that worn that they burred the bottom of the followers! So it is scrap and the followers and maybe the head I will investigate further tomorrow as I was that pissed off I grabbed a beer and came back in the house. Anyone had problems with these? What camshaft is most folks using nowadays?
