Big shout out to @Gerald for help with the oil pressure gauge settup. Thanks Gerald for helping with this build, probably for the best version of the widowmaker yet! Thank you for the pressure gauge, oil switch unit you built for me. #teamrocketeers! I couldn’t do this without all the help, from the 1st post to where i am today thanks team.

Not so fast on the valve settings rookie, not as perfect as i said, mine were too loose. Konrad found my measurements to be flawed, the angle of the feeler gauge to the bucket is critical and definitely changes the value of the clearance I learned today, a strait feeler gauge is not perfect for this job as a short curved tip is better, after a bit of back and forth, hashing out how we do or feel for this adjustment, he was right as his technique proved to be accurate and mine not, but we got on same page ( i got on his page) and we came up with same clearances after each doing them taking turns not sharing #s, made needed changes and i have ordered 5 shims to wrap up valve lash settings. We were suppose to set intake center lines today but i a little corrective action was required first.

Always good to recheck your work maybe the day after. A mistake isn't a mistake until you let it go. Rockets aren't the easiest to adjust the valves, go - no go is a good check for adjustments. Glad you followed up. Even with the standard shim on top, I bend the feeler gauges to make it easier to check clearances.

Looks like you adjusted shims to achieve clearances to the high side. Is that preferred over setting to low side?

I think as long as youre in spec youre ok, I was shooting for .178 on exhaust and .127 on intake, and i wanted all the same, shims were not exactly as advertised, i could dial in the outlier on exhaust but, long as the cam maker 
is ok with the clearances you end up with you’re golden. Luckily ive been given a thumbs up by the man in the tin shed so im definitely moving on.

When rebuilding a rocket, install cylinder head on engine and torque to spec, chain on and timed, before doing your valve adjustment. 
They tightened, all are still in spec except exhaust #3 went to a .127mm on both and will have to be corrected. Learning and sharing all, even the stuff that makes me look and feel like homer. But im gonna get it right.

Getting cams in position coming along, close on intake, trying to replicate numbers on all 3 cylinders so i know im accurate, before i make the call to see if i can proceed, a few shots of working the intake side, #1 intake is coming in at 105.5 center line consistently and it needs to be 105 so ive got maybe one more adjustment, a bump advance on cam gear should get me there, a very small bump, no numbers on gears so im working it. This part is so exciting, waiting for the valve to open, exhilarating, but when it closes, oh my i can barely stand it
fixing to be a party in a few degrees, a real bang.

After 3456 attempts to get correct i THINK ive got it, checks over and over, tdc checked with dial and hard stop, so im moving on to a starter cylinder pressure test, fingers crossed 210. I sure did miss sparkys and crazystagehands help this time but sparky had schooled me up and told me i gotta fly 
i was ready, ok that last part about being ready he didn’t say
