Valve Train noise

So ever since I rebuilt my heads and did all the gaskets, I've had a sound of metal nocking around. It seems like the sound level is based on the amount of throttle Im giving it. I thought it was a number of other things but I ruled them out. When I was putting the rocker arms back on, I only torqued them to spec, I didnt check any clearances nor remove pushrod lash... Im really not sure what the correct process is for adjusting the rocker arm nuts. I was told I could remove the valve covers and see that way, but it seems like a decent amount of work and I have cork gaskets and would need to replace them. Any Ideas on where to start... I really dont need a pushrod bending or worse. I was getting some gas in my oil ( Gas in my oil ) its all in this thread. Now I'm wondering if I had an exhaust or intake valve not opening is it possible that would cause the gas in the oil too? Just some thoughts, thanks in advance!

Maybe the rocker arms hitting the valve cover

Even if it was torqued to spec? How bad would that be? Should it be first on my list to check and will I need a replacement gasket?

Seems like the noise is getting progressively worse. Im pretty worries about it at this point. I don't know what my first step should be...

Pull the valve covers and take a look. Get rid of the cork gaskets while your at it

What kind of gaskets should I get? Where from? Whats the correct procedure for adjusting the rocker arms.

I got the ones that are rubber with a metal film in the middle. I think FelPro made them.

Sounds like your valve train is misadjusted. Valve could be staying open or closed.
Does it have a real bad idle?

Did you put different rockers in like 1.7? What kind of valve covers and heads? Your rocker could be hitting a baffle on the inside. First thing would be to pull the valve cover and look for signs of them hitting. Make sure you look on the underside of the cover also.

No, idle is alright, I believe I figured it out today at the garage! So I believe it was a loose header on the driver side. Torqued them to 24ft/lbs and it is almost all gone.

I always use copper gaskets and lock washers. I hate exhaust leaks!! They are easily mistaken for tapping lifters, etc...

And that works alright? I have what looks like an alum gasket that spans all of them... seems pretty standar.

The gasket is standard. My car is turbocharged and I don't have any leaks

Haha, that is exactly the one I use. You don't have to use it though. You can use gaskets, that's just how I do it.

I have seen a buddy of mine do that and swear by it but I always run the felpro 9001's from advance(think that's what they are, been a while since I've actually needed to get any)
