Thank you. Was pretty sure it was something simple. I'm going with the Shermans on my crate stock engine. so, this will soon be an issue I need to understand.

Cliff will tell you, you have to adjust them a couple of times to get them "dead on". I use a .004 feeler gauge and make the first run through as close as possible, setting them by firing order. i start the car, bring it up to temp. shut it off and pull the covers, run through the valves again, by firing order to double check. you may have to "cheat" the lock nut to snug some up. i have never found any too tightm only loose, but it could happen i guess. then after 1 or 2 passes at the track, i pull the covers again for a final check. you MAY find 1 or 2 this time. reinstall the covers and run it. I havent tried the EOIC method on these stocker style engines, but i havent had any trouble either.

This is what I use.

I've tried every method there is and in my opinion EOIC by hand is the only way it is accurate on a stock eliminator style cam. I am not talking about other cams, just stocker cams as they have the most radical ramps and are much more "touchy" than any other ramp there is. I just do one cylinder at a time, front to back on each bank. I don't go anymore than approximately 1/3rd valve travel or movement and then make the adjustment.

For you serious race car guys with gross duration figures in the 320 plus region you can use the firing order sequence but instead of adjusting the #1 valves at TDC #1 adjust the previous intake rocker and the next exhaust rocker. This ensures that the lifter is on the absolute base circle of the camshaft.

This is the info I was referring too.

I concur.

This is the most accurate method, in the FO as prescribed by the S.A.E. in their manual.
