I can't seem to find the procedure for setting the valves on a h gas engine in the I&T book. Could someone tell me how to adjust them. Looking for which valves to be set when on #1 TDC then roll 360* and set the rest. Thanks

Not exactly what you asked, but it works well, and does not require precision in engine placement.
Hot if you want to means run it for 10 to 15 minutes then take the valve cover off and adjust. It does not need to be working hot, just into good and warm.
Valve Adjust Jim's way --- It is simple and fool proof. The process works for all engines with adjustable regular valves and any number of cylinders. Identifying the valve order is all that is necessary (given in this process for the IH 4 cyl gas).
I do it this way others do a different system. It must be set cold first, so setting it twice (or once) is normal Get the specification.
Set the intake valve on cylinder #1 (Front) when its exhaust valve just starts to open.
Set the exhaust when the intake just closes.
These are the two positions that can be seen at the springs and retainers for each cylinder to be as far away from a lobe on the cam as possible while still knowing where it is.
The order is (front to back EI-IE-EI-IE)
Look at #1 valves, Turn the engine till the Exhaust just starts to begin opening (moves) then adjust the Intake valve. Rotate more until the intake just stops moving after having been open) and adjust the exhaust. Treat every cylinder (pair of valves shown above) the same way, remembering they switch places between cylinders) I put a rag over the ones I have done to keep track of progress, and avoid mixing what I am looking at.

Thanks for the quick answer.

If a picture is worth a 1000 words then what is a video worth? Not my video but a nice one nonetheless....
