Ok I just looked down one of the cylinders with a bent push rod. I can't see any evidence that a valve hit a piston. The pistons have 4 valve reliefs in them so maybe I got lucky. Do any of the chain parts stores carry a length checking push rod ? or does anybody have a picture of a home made one ? I have plenty of push rod parts to make one out of ... hahhahahah
if you have a hollow pushrod you can make a checker , just cut an inch or so out of the pushrod and tap the inside for 1/4-28 and get 2 nuts and a length of 1/4-28 threaded rod .

Did it start and run ? Did it die right after starting , seconds, minutes ???
He finally posted that it ran 20 minutes. That changes things a bit...
I was under the initial impression it only ran for a few seconds.

I'm making a push rod length checker now. I'm hoping that my pushrods were just too long and caused the problem.
when it was runnig for 20 minutes was it a clicky clackety mess? did it run ok? if they were too long you probably wiped the cam. Have you drained the oil yet? Drain it and toss a magnet in it, then pull it out. Or if you have a magnetic drain plug..well you'll know when you pull it out and it looks like Beaker from the Muppets.

I didn't get to take a picture before my neighbors 10 year old son grabbed the remote start and pushed the button chopping my camera of in the cylinder. I'm in the process of trying to get my camera out of the cylinder with my old borescope.
Holy crap! Are you freaking kidding me??!! Lucky your fingers / arms weren't near anything. Man, this is just a bad time, you can't make this stuff up!. Good example why disconnecting the battery is a good idea. But cripes, you shouldn't have to worry about that type of hazard.

it's not your pushrods. I'd almost guarantee it.
if the pushrods were too long, then you'd have lifters bottomed out and hanging valves open.
who's valve springs are they? Hughes recommends their own springs/retainers to run with their cams, especially with the whiplash cams.
put a good pushrod into the valve train, and slowly crank the engine over by hand, again and again, let us know what you find. does it crank over smoohtly the whole way? do you feel anything binding up? can you visually inspect the valvespring/valves to ensure the coils are not binding up or the retainer hitting the valve guide?

Yea I had a clear shot of the piston and there is definitely no damage on the piston at all. I didn't get to take a picture before my neighbors 10 year old son grabbed the remote start and pushed the button chopping my camera of in the cylinder. I'm in the process of trying to get my camera out of the cylinder with my old borescope. so I've been looking at this piston for the last hour or 2 and it has no damage on it . Man I should have taken up gardening. Hhahahah
I admire you for being able to laugh. Wow.

I bought the whole Hughes setup.... Cam, lifters, springs and retainers. They told me that my springs would be fine because they only had 50,000 miles on them but I bought them anyway. I had them installed by a machine shop that has been doing work for me for years with no problems.
I think I will leave the camera in the cylinder and get the push rods checked and measured because it sounds like the heads are coming back off anyway.
