Finally got him cranked up late last night, I inquired some advice from my cousin, he told me they weren't hydraulic lifters and to set clearance for about .0015" Before that I followed what someone told me, tightened the rockers till there was no play, then 3/4 more of a turn, and that must have cause the carb problem. Anyway, we didnt make clearance to .0015", but .015" (we just weren't thinking), regardless, we hooked up the battery, and putt-putt-putt-VROOM! A couple of the valves are still clicking like a typewriter though, and we can't find out which ones they are, any advice would be great. Plus, my truck smokes like Auschwitz!!!(It's white, bot black, so at least we know the rings are good :D) Now, i think there are 3 reasons this is happening. First, there is white lithium grease coming out of the new head i believe as it coated the inside of the valve cover. Another reason is the valve clearance might have something to do with it? The final reason i think is not everything has seated properly yet. Maybe all these things are reasons, truth be told I don't know. Was hoping yall could help me with that one. In lighter news, I just basically rebuilt an engine, and I'm only 16, and it RUNS!!! You guys were right, I feel proud of myself now, it's better than scoring a touchdown in a high school football game! Also a precaution with running your engine without a valve cover, WATCH YOURSELF! It took about 5 minutes of running for the oil to start squirtin, but once it did.....dear God...It soaked my brand new air filter, drenched my buddies girlfriends new "North Face" jacket (for those who don't know what that is, it's a $160 waste of money girl jacket), good thing it was black already ;), filled up my cup of Coke and lubricated my right eyeball quite nicely!
