MODS!!!!! This guy has two open threads on this same topic in this forum and one in the race forum. I'm getting tired of opening a thread and reading the same old whining and guesswork answers. To the OP: Take the doggone heads off, but before you do, check valve to piston clearance using a light spring and degree wheel. Get V/P measurement at every 5 degrees from 20 degrees BTDC to 20 ATDC. While you've got the spring off measure its compressed height. Also check the valve stem seal to retainer clearance. Measure the actual pushrod diameter between an end and the bend. If they all check out it's valve guides. Between now and the time you get that done don't start another thread about the same thing.

Was the gas it ran on new? Old gas will leave tar in the intake tract and when the engine cools it cements the intake valves in place. When you crank the engine again the pushrods bend.

It looks like it was coil bind I only have .375 travel on the valve. I found an extra spring that was installed that the machine shop says is not supposed to be there. I have the outside spring the damper and a spring inside the damper. I'm taking the extra spring out and checking it again. I will let you guys know what I find.
How do they know it's not supposed to be there , the Hughes spring may be a double spring and if it is the spring seat on a factory head is not cut to accept that type of spring arrangement ....
Are the heads off yet ?

No the heads are still on and they are staying on. The extra spring was the problem for some reason Hughes shipped them with the extra spring and Hughes says it's not supposed to be there. The machine shop just installed them the way they received them. Yes they should have checked them but right now I'm just happy to have the problem solved without having to take this thing back apart. Now I just need to get the camera out of the cylinder and maybe I can drive this piece of crap.
now that you have said that you will be pulling that head to get the camera out ...
good luck ...

If it went in through the plug hole why wouldn't it come out the same way?

The issue will be grabbing it to get it out thru the plug hole, I'm guessing it wasn't much smaller than the plug hole.
If it were me I'd almost be tempted to pull off the intake , pull the intkae valve spring , make sure the exhaust is closed , put the plug back in , lower the piston some and open the intake valve to the point that the retainer with locks is sitting on top of the guide and use a shop vac to try to suck it out the intake port ...
