I have seen the crap gas valve sticking story many times.
Most of these stories come from people running old engines on modern non zinc oil.
I also believe that running modern non additive oil through brand new valve stem seals makes the valve stems run dry as a bone during initial startup and break in.
And the oldest older than dirt break in mistake is to spin the oil pump untill you see oil at the rocker then call it good and fire it.
On dry valve stems.
Putting an engine through a dyno test is not about finding its horsepower or torque.
Its about finding that engines potential failure points and correcting those failures.
Dyno testing is only a measure of what that engine was capable of during that particular run.
Part two of the only reason you should ever spend the money to dyno test anything is when you take it apart to see what failed and how to correct that.
Other than that?
You just paid somebody to beat the hell out of your new engine
And you got a hat and a tee shirt.
Dyno numbers only matter to people who aint never ever ever going to run down the track.
We call them "Pit Posers"
I would take a run but my tires are bad, or I have steering problems, or my transmission is kinda sketchy.
Blaah, blaah ..
Pretty cars, lawn chairs in the trunk, wife waiting for the turd to drop dead
Big Badass dragracer.
The douchbag who leaves his poor wife alone with the car so he can wander around and get a ******* woodie because he figured out that you have 1968 door pull knobs on your 1969 roadrunner.
Those guys are no different than people who collect beinie babies.
Numbers dont mean ****.
You dont have that kind of money.
Dont spend a bunch of money just to ******* blow it up on the dyno.
The lights on the track will tell you all about how fast you are running and all about who you are as a team and who you are as a driver.

I was thinking you had the wrong rockers before I scrolled down to read that you discovered that you had the wrong rockers.

Really sucks. Such a minor "problem" creating devastation. ****** me off that GM went to self-aligning rockers in the first place. Too much Ford engineering going on at GM. But what are ya' gonna do? It's not like they asked my permission to use self-aligning rockers.

That’s about the same thing I’ve told my customers for years and years. The HP and Tq. Numbers are the bonus on the paper you get. The real info is did it break if it did you can fix it before installed into the vehicle.

Tough break. The only condolence I can offer you is that you are a little wiser now than you were before. And next time you talk to someone building an engine you will have a story to tell and a lesson to convey.
