curious about valve lash setting/check

alright guys, this is what I found (and did it numerous times to check), back and forth on the push rod vs. spinning for drag, and it might be my touch here, but as I said...numerous times, the back and forth on the push rod seems to get me 1/2 hour clocking earlier, consistently! don't know if that's a big deal, but I thought I would throw that out there to see if anyone else agrees, or disagrees. here's the big question: I noticed there was pressure on the #5 intake, #7 intake, and the #7 exhaust when setting. is there a reason for this? although I did this meticulously, I will run through it again tomorrow....practice makes perfect, right? curious about the pressure on those 3 valves. thanks again, so many helpful inputs, I really can't thank you all enough. waiting another 15 minutes to set the t-stat housing to torque, then....as 69 said, I will wait the 2 days curing time. so......if it isn't snowing/raining, I'll hopefully be out on Thanksgiving.
