Wow that is all wrong! If your arms are straight, you can't get the front wheel nearly as high as you could, and you pretty much have to be rolling. NFG if you need to hold it there for a few seconds while you hop and try to figure out the best way to get up onto that log/bench/divider/whatever you're next to.

At least we know the fuel injectors are balanced!
Picture unrelated:
Found that picture of a dollar bill versus 351C-4V intake ports. They are HUGE!
Just seeing them makes me want to build a bogus Boss 302 with a set. No idea what car I'd want it in, but the idea of the engine makes me giggle like a schoolgirl.
More pictures from work. Failed 3100/3400 intake gasket.
This one wasn't leaking coolant, just had a really bad misfire on one cylinder. Smoke testing the intake had a lot of smoke coming out of the valve cover. Yanking the intake manifold showed this.
Dexcool doesn't flow through the intake ports. The intake gasket problems that these engines had were NOT because of the coolant, it was because of the inherent problems with trying to use a plastic backing for the rubber O-rings. This sort of failure is extremely common with the Vortec V8s, the long unsupported span can sag down and cause a big vacuum leak and misfires in the center cylinders, but this was the first time I encountered it on a 60 degree V6.
Also, check out those valve angles. I seriously dig these little engines. Roller pedestal rockers, beehive springs, massively canted valves, ports that flow better than fully worked-over race heads from the 80s... wish I had something that would take one of these engines! Maybe someday.
In reply to Knurled:
Interesting. Both sets I replaced failed at the water passage on the front of the engine.
I had one that lost two sets about 100K miles apart. That engine has almost 300K on it now and still runs great. Other than the gasket problems, they are great little engines.
Something like this would be a lot of fun.
73 year old Donald Johnson wanted to work on his El Camino Saturday morning so he rolled it out of the garage, but it kept rolling.
He couldn't keep up, it rolled over and broke his leg before stopping upside down in the Yakima Washington canal.
