351m bent pushrods
#16
See post #10 and then look at post #5...where the pushrods are on #1 exhaust and #2 intake. Nice openings in the head. Same with 3 and 4, 5, 6, 7 and 8. The smaller pushrods holes allow a magnet or Chinee fingers to get down to the lifter, pull it out and with the magnet and pick/screwdriver, one can maneuver the lifter over to the larger openings and pull' em out.

I guess I get it. There are usually too hard to get out with a magnet if they have been in a while and the grabber requires a straight shot. Good to know.
Be sure to put them back in the same hole.
I guess I made a mistake. I made one once in 1974 when I thought I was wrong but turned out to be right in the first place.
LMBO!

I pulled the lifters and checked them out for a second time. They are a little warn but no light from the middle. I used pb blaster (?) on the springs and the tapped the valves with a hammer. Some whent -thud- some whent -ting- so I lightly tapped them to see if I could get all of them to -ting-. Then i put the new push rods in and let her run. Everything looks good so far, just wanted to say thanks for the help.

Thank you but I don't think I will be that lucky. I put the valve cover gaskets on today adjusted the new carb and ran it and it still smokes out the back. I thought after finding the push rods off the rockers it may fix itself but no go. It dose not have water in the oil and it runs good. The smoke is white but dose not smell like blown head gasket.

It's about 90 f out side and the truck was running for about 10 min. I noticed it when I started the truck for the first time. When I would rev it up it would get worse and was less when the truck was cold. But at that time the carb was shot and I had the pushrods problem. When I found the push rods off the rockers I was so sure that was the problem but its not. It's not a blown head gasket, the engine runs good, it's not blue like oil, it's not running rich. The only thing I can think of is if the gas is old. The guy told me he just filled it with 5 gal before it was towed to me but now in not so sure that gas is good. Can old gas make a car smoke?
As for a cam I have no idea what was done to the truck. The engine is a 1978 and I thought they ran rotators in 1978 so to me I think someone has been in the engine but I have no idea.

Could be a touch worn on the guides or stem seals, not enough for heavy blue smoke but enough for little puffs, old gas is a possibility but If it got worse after warm up I would have to think blow by or a top end sealing issue. Not necessarily enough for a full rebuild but a worn guide or burnt valve or two would add little white to the exhaust. Mine did that when I first got it (now prepping engine #6) but if it's a daily it's up to you how far you want to get into it

A few things come to mind;
Old gas.....you betcha old gas will make an engine smoke....not like a SoCal grass fire in August, but somewhat like roadkill burning on the grill.......and smell very bad.
Exhaust rotators....yeupp, used in '78 and up stock M block heads. Chances are good that if they have been replaced, it was because an aftermarket cam, etc was installed. That video did sound like a "bigger" than stock cam.
I know you have a vacuum gauge...hook it up and watch what it tells you. You can eliminate or verify valve, valve guides, valve springs, ignition timing....etc...
