any help is appreciated i just dont wann tear into this before i have an idea of what it is
I know its not a rod because its at 1/2 engine speed so its definately valve noise i just dont know if its a broken spring or if its a sticky valve smacking wierd or what

i found my noise not saying yours is the same but i have a bad head. before i bolted it to the block it sat outside for a few months and the cam bearings got rusted but when i felt the cams they spun fine after running for about 5 minutes the cam bearings were completely gone and now i have a "cam knock"
