I can get 14 rocker nuts on, in order to get the other 2 on i gotta turn over the engine. I installed the cam, timing set, and hub myself..

something not right if you can't get 2 of the poly nuts on. The 2 cyl you have issues mean the base circle of the cam is not on th elifter...the lobe is.

If the cam is installed right, you are not lashing valves right. Either the I/e method where you do 1/2 then rotate engine 360 degrees and do the other 1/2 or doing each cyl by making sure the valve you are adjusting has the base circle of the cam and lifter aligned correctly

FWIW I have always used this method with engine off

with #1 cyl TDC (firing position) adjust:

INT: 1, 3, 4, 8
EX: 1, 2, 5, 7

Rotate engine 360 degrees (#6 cyl firing position)

EX: 2, 5, 6, 7
INT: 3, 4, 6, 8

What I had going on was, cylinder 1 TDC I could only start 14 poly nuts, seems like the other 2 pushrods were at max lift, not leaving me enough thread on the stud to start poly nuts, at that point I was not trying to find zero lash, just putting rockers and nuts in place. Not sure what I had done, I just started over tonight, done what Steveo said, the engine cranks fine now, noticed tho i messed up the threads on a couple poly locks, think that's why it was hard to do the 1/4 turn preload, still don't explain slow and hard cranking. I was thinking it might have been the new springs, there still ticking, might have taken a bit to get them broken in? don't no. Compression test tomorrow.

trying to figure out why after i set my valves, my fresh rebuilt 355 is hard to crank over, no spark plugs, throttle blades open, new charged battery, booster cables straight to starter, slow cranking, before i set my valves the engine was easy to crank by hand, but now its really hard to crank, with spark plugs in cant hardly crank it over by hand, tried to use the starter and melted booster cables, after i crank it with no plugs i can hear something under valve covers creaking, took valve covers off and everything looks normal, had some oil flowing out of a couple pushrods, the reason i was cranking it was to prime the engine with oil, just wondering if the Pac 1212x springs, or ls7 lifter, 1.6rr and hotcam would be causing this, kinda seems like its something to do with valve train, i only put 1/4 turn preload on lifters. Seems like without spark plugs when i rotate it by hand to goes good for a bit then brings up in something. springs binding up maybe? anybody have any thoughts on this? starting to think bad valve adjustment? bad lifter?

Did you ever get the oil to come out all of the push rods
