Problem removing inner valve springs

May the force be with you
great heads up AJ
congrats Dustin- keep us posted
what are you using for break in oil with your new build
I recommend a blended specific break in oil not DIY additives- pre lube with the drill
and double-check everything so it fires immediately, and keep the revs up
Fixed it for ya,lol.
My tips;
Push the car OUTSIDE and at least 4/5 car-lengths away from any wood buildings or flammables;
Do not set the fire-extinguisher down beside the left front wheel! Or even anywhere near the car; better to have to run for it then to not be able to get to it cuz the fenders are on fire!
Have an emergency shut-down plan. I use a long jumper wire feeding battery power to the ignition system. After it starts, I turn the key to off, and run the ignition off the jumper. If I need an emergency shut-down, I just pull the jumper.
Have running water close by and an IR gun.
I never break in an engine with a new thermostat in it , or any stat at all; just a restrictor washer. I can't tell you how fast things can go wrong when the stat won't open,
or if you panic.

But mostly; set the daymn timing right ! and plenty of it.
As soon as the engine fires: get her up to speed and then tug on the Timing until the rpm peaks and then retard it a couple to a few. . Forget what the timing light says at this point; just give her what she craves; could be 40 to 50 degrees. Then pull the rpm back down to 2200 to 2500.
Check for leaks, especially gas! If you spot a gas leak, shut it down! to fix it; Do not try to fix a gas leak on an engine running at 2200plus!
OK eyeball the gauges and sit down.
Keep an eye on the temp gauge, and grab a beverage; 20 minutes at 2200 is a really long time.....
I used to involve two or three other guys on this business; one on the fire extinguisher and emergency shut-down, another on the waterhose, and me the maniac overseer.
Above all; If you feel the need to shut her down, DO IT!
Don't panic;
The cam will be fine when you start over.
And if not; Better to sacrifice the cam than to lose the entire engine, or worse, the entire car. You got her insured?
