Heres my step by step method.
Step#1 remove valve covers.
Step#2 remove spark plugs (makes it easier to turn motor by hand)
Step#3 adjust valves like Tod said> "When the ex starts to open, adjust the intake. When the intake has opened completely and is on it's way closed, adjust the exhaust"
Step#4 re-install valve covers and plugs.
That pretty much covers it.

Then You said "I usually start with TDC etc...." that implies that you already know how to adjust valves and that your only issue was that you now have a 4,7 firing order swap cam...If you didn't already know how to adjust valves you should have said so, I would have been more specific.
Open hood.
Unbolt valve covers by rotating bolts or nuts counterclockwise with
the appropriate wrench.Remove coil wire(Accomplish this by firmly grasping the rubber boot on coil wire and pulling...I recommend the engine be off )
pick a cylinder...bump the engine over with a remote starter (by pushing the button ) until the exhaust valve on that cylinder starts to open...stop moving engine. Now insert a allen wrench in the poly lock on the intake valve while holding the outside of it with a box end wrench.Break set screw loose by rotating allan wrench in a COUNTER CLOCKWISE DIRECTION. and back nut up by turning it counter clockwise..insert feeler gauge.. tighten nut by turning wrench clockwise until there is firm drag on the feeler gauge...hold hex with wrench while snugging down set screw by turning it clockwise... recheck with feeler gauge..it will probably be looser, then snug down with hex wrench( clockwise) the last little bit. Check with feeler gauges.(go no go with .001" bigger and .001" smaller) Now bump motor over until that valve opens all the way up and is on it's way closed..repeat previous process on the exhaust valve. That's how I do it...I start on one side and do them all then go to the other side...takes a little longer maybe but to me there is less chance of missing one. Just my opinion everyone has their own way to do things.

No one is being a smart ass here, although some made those remarks. There is no special way to adjust the rockers on a 4/7 swap cam. You just adjust them one at a time once the engine is warmed up. Use a breakerbar or a rachet and turn the engine over until the exhaust starts to open and adjust the intake on that cylinder, same for the exhaust. Don't ever look for short cuts on a race engine, it will bite you in the butt. It's not fast and it's not quick, but it's the right way.

You guys might as well give it up. Like was said, it's the cultural difference that we AMERICANS can't match. I've been through this same sh@t with another on here and you just can't dumb it down enough. Good Luck! :roll: :roll: Dave
