New aluminum valve cover doesn't fit??

I have a clearwater 4.0 conversion head and the red aluminum valve cover from Crown doesn't fit? Plus I cant tell why, at first I thought it was the rocker bridges hitting but its not. all the bolt holes look dead on it just wont sit down completely onto the head.

See how the end of the valve cover is tapered down in the front is it like that in the back that taper could be the cause.

What valve springs are you running?
It is known that some larger diameter springs interfere with the valve cover.

My guess is the baffles for that valve cover ports (pcv and vent) hang lower and are hitting. What gasket do you have? The cork gaskets add quite a bit of height that may clearance it.

Agree with gmakra. I have the Clearwater head with as valves and had to grind down the valve cover around a couple of the valves for it to sit correctly. There is plenty of meat on the valve cover and it just needs a little grinding to sit flush.

It's not the ports, those I could measure. I'll try put some masking tape across the valve springs and see if I notice any marking after setting the cover back on

What year is the head setup? As those valve covers are said to usually only fit 93-04*ish.

Not sure what year, it's not stamped. It's whatever year Clearwater uses . Gonna mask off the inside of cover and see if I can notice where it's hitting when I get home today.

I'd be trying to get a hold of Clearwater and ask.

Clearwater wouldn't even tell me what springs they used...trust me they aren't too helpful. I bought a 500 head and had to do 300 dollars worth of head work for it to work with my cam....( long story)

Well got around to masking the inside of valve cover and looks like the first and last valve spring retainers are hitting. I'm gonna first file the outside where it's tight against the ARP head bolts (drivers side) and then try and carefully grind the inside a bit

Sounds good. That's exactly what I did. Like I said that valve cover has plenty you can take off and as you can see it really doesn't need that much to work. I used an air die grinder and had no issues.

Now now, we did determine part of that whole debacle was due to them not having received all the pertinent info......

As for the interference, it is a pretty well documented problem in the stroker community and came up in several google searches when I was researching cams for my head swap. So it's not specific to clearwater heads, per se.
