First setup I tried was 0.008” intake 0 exhaust. Ran it. Nothing bad happened but the exhaust note at idle was odd sounding. Didn’t feel confidant about tightening them down to zero. Went back and set the exhaust at 0.005”. Rotated the engine to bring oil pressure back to the lifters. Fired it up again with no accessories, so run time was limited. Didn’t tach it up much but on the middle idle step it was smooth. At low idle it had a nice rumble. Tomorrow I’ll finish assembly and let it idle up to temp for 15 minutes to get the lifters normalized. Appears to take some time to fully bleed (oil in). Just my observation. Explanation below.
What I noticed from the first time thru then the second was how the lifters reacted when forcing the oil out. First time they took some significant force to bleed out. It was run for about 5 min after the first adjustment. Subsequent rounds the lifters gave up to fully depress the plunger took less force and some had minimal resistance.
I’m assuming the lifters will normalize and do what they do once they’re back in action. At that point I expect to leave them alone and not have to dick with them again.
