I can barely understand what you typed there...
Are you sure it's the valves making the noise? Are you running a stock valvetrain? If so, you may have damaged something. With a cam like the 727, with lots of lift and duration, paired with domed high compression pistons (how about the head? Milled?) you may have had some piston to valve contact. Check your compression. If you damaged a valve even slightly, it would probably make noise. It would definitely kill idle... and it would certainly show lower compression in one cylinder. Even if you do have an upgraded valvetrain, that still may be the issue. The SOHC setup can be dangerous if you don't take all things into consideration.
Other things to consider would be your distributor. Perhaps your rotor is loose or damaged. It's a stupid thing, but it WOULD rattle and make your idle suck.

did you reset the valve lash after the cam install

no its not the valves hitting the pistons comp has been checked and yes i adjusted the valve lash when i installed the cam it only rattles under a load like a hill or when i get on it hard but it doesnt do it when the ignition timing is retardedOriginally posted by Gen4Acclude
as for the idling problem it started about two days after i installed the cam it will idle for a few secs then idles up to about 2k then to like 500 up and down the diesneed h23 headComment

mine did the same shit untill i retarded the cam 4 degrees then idled smooth fuck the bitches that stole my car jan/1/2006@7am from montesano wa updated: The Warrens from Malone Wa were found guilty for possesion of stolen property in the 1st*and were ordered to pay $2489.69 in restitution, only cause the shell was not found

well i just got a adj cam gear maybe it will help me with my prob to thanx man ill install tom and try it thanx for all tha helpneed h23 headComment
-
i didnt even ask was it the idling prob or the valve rattle that retardind the cam corrected so how many degrees retarded is the cam because the stock cam timing is acutualy 5degrees before top dead center so should i retard it to -9 degrees or -4need h23 headComment

ing 15* +2-2*
cam 4* retarded from 0* fuck the bitches that stole my car jan/1/2006@7am from montesano wa updated: The Warrens from Malone Wa were found guilty for possesion of stolen property in the 1st*and were ordered to pay $2489.69 in restitution, only cause the shell was not found

that is stock ing timing are you sure that i shout run that high of timing with 12:1 compComment

please say it's not on pump gas.
Umm... you aren't running a 12:1 engine on pump gas are you? It sounds to me like you are experiencing massive detonation. You will need to go to your local speed shop and purchase race gas (probably 112 octane or better) for this engine to run properly. retarding the timing and adding some octane boost will let the car run, but you will definitely realize huge gains in power with race gas and proper advancement of the timing. Timing settings will also depend on how the cam is set up, I would contact the maker of the camshaft for advice. also you will probably want to run cooler spark plugs. Get your cam specs and call NGK for instance, and talk to one of thier tech guys.
p.s. this is probably not the best engine setup for street use (expensive gas) but could be killer at the track! Good luck.
