For starters, use the up and down method for finding zero lash. The spin method can throw you off because some push rods can spin easier than others, even while under a load.
"Method 1" has given me disappointing results, once done and rotating the engine a little by hand, some of the rockers were sloppy again. I'll never do them that way again. That procedure doesn't put all the lifters at the heel of the lobe, it's physically impossible. As far as I'm concerned, that's a fine way to go just to get the engine started, as long as you intend to follow up and adjust the valves the "engine running way". Method 3 is better than 1, but here is yet another procedure for setting the valves individually, which I prefer. It's a good write up too, and describes what's going on with the cam and lifters.

Isn't the up-and-down method just lifting it up and down until you can't anymore to determine zero lash? When I did the turning method, I tried lifting the rods once I thought I was at zero lash, and in some cases they didn't move, in other cases they did, so I tightened the rocker more until they didn't anymore.

I just bought an OBD2 scanner at O'Reilly and pulled the SES code P0100 "Mass or Volume Air Flow Circuit Malfunction" code, so apparently cleaning my MAF didn't take care of that either.
I ran it for a little more this afternoon, and the exhaust leaks and the valvetrain definitely need attention. I'm going to East Lansing for the weekend, so I'll have to tackle that next week.

So as you may recall I said before, I used brass caps to cap off the AIR fittings on my headers, like so:
Almost immediately after I started the car back up, the thread tape melted and the exhaust was leaking like crazy. So I learned that thread tape isn't good for heat lol. So what could I use to seal these without the sealant melting with the exhaust heat?
