Just to make you aware, the E1 and E2 specs should be the same for these things.
The head bolt torque is 220 inch pounds.
The intake and exhaust valves should be gapped to .004
Rocker bolts torque to 45inch pounds.
Rocker arm cover bolts torque to 60 inch pounds, there is no sequence for this.
The repair manuals from Briggs cover the whole 310000 series engine. Meaning a 310, 31P, 31C, 31H, 31A, 31M, etc... So if you have a service manual for a 31 series engine it's good for all of them unless noted on the front cover.
If you have any further questions please let me know.
