Thanks Nessal and +TSRAGR for your input and advice, very much appreciated! So I was able to take the measurements as talked about in that thread I posted between the valve shim and the rocker. You can totally just lift the rocker with your finger when the lobe is pointing straight up away from the valve shim or you can use the screw driver method at the rockers roller and lift up. Below are the measurements that i got on top of each of the valve shims on the Intake side. I drew a pic of where i took the measurement in red and the red value per lobe on the sketch corresponds to this. I started to measure the Exhaust side just to have those as well, but i don't plan on changing that side so i stopped.....for now. I just wanted to check to see if these measurements are looking right as they were almost all the same from cylinder to cylinder and small lobe to small lobe and big lobe to big lobe. I started with .008" and went up to .011" on top each valve shim on the intake side to come to these measurements.
If these measurements sound right, then awesome i did something right!
So now I'm trying to get to the accepted valve lash of .011" as stated by Phil of BOE and many others. So in essence I need to turn my .005 or .006 measurement into a .011 right? So next I will get down to the valve shims and take them off of each of the valves and measure them from inside the cap to the top of the cap ("cap" meaning the valve shim). Then i follow the formula from Boosted 2.0 which was posted on that other thread:
"Step 2 - Measure your cap between the top of the bucket and the bottom of the rocker for EVERY SINGLE valve. Record those measurements as measurement A
Step 3 - Remove any shims that are not at the spec you want and measure the thickness of those shims. Record those as measurement B
Step 4 - Apply the following formula: New Shim Thickness = Old shim thickness B - (0.010" - Measured clearance A)"
So when i have made it this far I can then order my new shims and then build everything back up again and we should be good to go.
Thanks for any and all input! I will probably do a complete write up with pics for anyone attempting this as I wasn't able to find a complete begin to end guide on what to do. Hopefully it will help someone out there one day.
