I have most of my motor back together. I was wondering what the valve lash is suppose to be set at, along with what valve cover gaskets are you guys running with the canton valve covers?
Im running 1.6 Pro Mags NSA, gm guide plates and 918 springs.

Valve lash is usually recommended to be between 1/4 to 1/2 turn after zero. www.shbox.com has a great writeup. Some people have seen increased power with less lash all the way to zero, but I would do at least 1/16 of a turn.

Here is the chart to his writeup, if it helps to see it..
I tried the 1/4 to 1/2 and mine was backfiring, it's a little bitchy.. :)
