I think maybe I... overtightened, give me the bad news Options

[brer]

Put the rocker assemblies back on my heads and drove home to san diego.
got very loud rocker noises coming from the engine

re adjust the valves.
drive it for a little while and bigger clacking noise and starting to lose power. (IMG:http://www.914world.com/bbs2/html/emoticons/sad.gif)

I think i *effed* it up installing the new studs and then torqing the rocker assembly nuts with my old torque wrench. thought i seated the studs properly, and torqued the nuts right, but now the valves dont seem to be holding an adjust.

so what the worst that could have happened?
stripped the studs from the heads right?

you mean like grinding down a cam....how often does that happen?

Like, grinding the lobes completely off, and eating up a 1/3 of the lifters.

About a year 1/2 ago, I had 2 cams go flat, back to back, the first 1, reason was up in the air? (operator error, assembly, breakin error, the heavy chevy springs I run ) the 2nd one, prompted phone calls, not only my 2 but a couple others cam back flat also.

My supplier, contacted WebCams, Scat, and they also had cams come back flat. (IMG:http://www.914world.com/bbs2/html/emoticons/smash.gif)

Do, to that they all get there cam cores from the same supplier, the thinking was, it was the cams, but I had 2 cams prior to the ones going flat, and no problems, and they were from the same batch of cores. (IMG:http://www.914world.com/bbs2/html/emoticons/smash.gif)

It, turned out to be lifters, causing cams to go flat, I 've been very leary of new cam and lifters since then. (IMG:http://www.914world.com/bbs2/html/emoticons/smash.gif)
