I just pulled the Roush 200 heads off to find some of the valves have made contact with pistons and one bent valve. The "A" hole that built my engine sold me these heads refurbished. I have learned one thing, I will never buy refurbished anything agian. I have also learned that I don't want these crapy cast iron heads anyway. The $650 I lost will have to be considered "stupid Tax" Is it possible that the 2.02 valves in these Roush heads are too big for stock pistons and that is why they hit pistons or Valve float? I am looking at buying Edelbrock Performer EDL-60329 Cylinder Heads. Anyone using these?
Bent Valve was the problem

Yes that is exactly the problem. Your builder should have checked piston to valve clearance.rrudholm said:
Not Sure 
But as I understand it
Valves that big only work with our oem shortblock if they are canted like TFS and the like.
Hate to see you had the issue
Maybe you can get them back in shape for just a little cash and sell em to go for Plan "B"

The heads are not junk it was 100% install/parts match up/combo choice. It sucks to hear about but not the heads fault.
Why not notch the pistons and get the bad valves replaced...it would prob. be cheaper and would work then.

I used stock length hardened push rods with a Crane 2031 cam and Trick Flow 1.7 Rockers. With my new 347 combo im using the same pushrods, and rockers, with an FTI cam and my geometry was great.rrudholm said:
I'm wondering if it was not really a mismatch but rather the springs are too weak or the builder had the rockers adjusted too tight from the start because this thing was running great up until I reved it real good and hard. I got on it some what before and nothing hapened?
oh Ya, West Michigan Machine in Muskegon, Michigan. He does not want to own up to the fact that he did something wrong. The word on the street is that this company had a good reputation and now it's not so true any more as it has changed ownership. I didn't know this going in. I have analyzed closely what has happened with my engine and believe it was valve float. I'm going to take these heads to another machine shop and see if maybe he has the wrong springs. I know that with a roller cam you need a pretty beefy spring.
