I figure thats all i can do, Adjust the valves and see what happens.

Id go back to using the drill to prime it, even if it takes 10 or 15 minutes, its better than running it and possible damaging the push rod ends or rocker arms.
if you have a high presser high volume oil pump they may have in staled restrictors in the back of the valve train galleys to keep the hydraulic lifters from pumping up to much when at high RPMS???maybe??? which in turn takes for ever to fully oil up, I have thoughts in my 350, which I'm running a solid lift cam so I really don't need that much oil on the top end. when I start mine up (cold) the oil presser gos to 80-90 psi at idle and I'm running 0w-30 Mobil 1 synthetic
just my .02

can i just sit there and run the drill wide open? Do i have to worry about too much oil pressure?
or should i try and keep it around 60 psi?

Well that got oil up to #8 #7 and half of number 5#
The battery doesnt last too long like that lol.

no, let it rip, the only thing to worry about is burning up your drill....... well unless you have some 10 hp drill that dose 10,000rpms then I might feather the throttle or keep it under 100-120psi or so

I just went down and ran the drill again, the oil doesnt seem to want to go past number 5, or number 8.
Im thinking about starting it, and seeing if itll pump up the rest. But then i dont want to damage anything... what do you think?

i would personally try and get all the lifters to pump up before running it, might help to loosen the rockers a little but i don't know if that will help or not

Try turning your crank a quater turn and prime it 4 times that's what I had to do I also put a hot plate or heat gun on the pan for a awhile to get the oil hot and thin

well I ran the drill some more, and the oil continued to come from the same pushrods...
Finally just started the motor, revved it a little, and watched for awhile... Kinda nerve wracking lol...
Anyway Oil is now coming from 8 7 6 5 4 and half of 3...
Im thinking about Adjusting the valves.... 1/4 turn lash. Tossing the covers back on, run it, and see what happens...

thats what i would do its under warrenty right? screws up take it back or find another place to get your motor done at seems like the people who built do a hack job

When I got my motor from them and put it in it ran like shit and made alot of top end noise, had to go in and readjust the valves. Called them up and told them that I had to adjust the valves and they weren't done right when they built the motor, they told me that any GOOD mechanic would adjust the valves before he installed the motor and it's my fault. Also had to have my intake planed to match the shitty angle that they had the cylinder heads @, once again they said it was my fault that I took too much material off of the intake when I cleaned it. Anyway motor is still running good in Rebel's s10 but I will never go to them again. Hope yours turns out better than my experience with them, hope to see you @ summer bash.

I drove it around yesterday, after we messed with the timing a bit, it ran pretty good. Itll break the boggers loose on the street. Im gonna bring my timing light, and mess with the timing a little on thursday.
Yea, i adjusted the valves on mine too, I had to do it initially with the engine off, all the valves were clacking, and i couldnt tell what the hell i was doing. They quieted down after the first adjust, then i re did with the engine running, just because i feel more comfortable that way.
Still didnt see any oil coming from the rockers on number 1 and 2. But screw it, i put the covers and im gonna run it. Maybe it just needs some more run time...
I WILL NEVER go back to Cylinder head specialties. Its to the point where have no peace of mind with this engine.
See ya at sand lake...

I'm hoping it will work out for you. Maybe run some lighter weight oil (10-30) in it after the break in oil is out. Marvels mystery oil is good stuff. I’d put one quart in it and take it easy while breaking in the motor and letting the lifters prime the rest of the way. It sounds like it is making good power! You just have to get the lifters working and you should be OK.
How is the oil pressure when warmed up at Idle? What about 1500 RPM?
Rule of thumb. You need 10 lbs of oil pressure for every 1000 RPM to keep the moving parts from hitting metal. So at 5,500 RPM, you need 55 PSI of Oil pressure, but at a 1,000 PRM you only need 10 PSI to be OK. Now this is the minimum oil pressure... Ideally the oil pressure should not go above 80 PSI. With high volume/high pressure oil pumps, I've seen them pump so much oil that the oil can not drain down back through the motor fast enough and ruin the motors that way as well. Plus too much oil pressure makes gaskets leak. I think the best oil pressures are from 30 PSI at hot idle to 65PSI under wide open throttle at peak RPM’s.
If the rockers start “Squeaking” because of no oil, you may need to replace the lifters down the road. If you have to replace the lifters, submerge them in oil for 24 hours. Press on the lifters (compress the springs) every once in a while to get them good and primed to get the air out.
