so far the liift is good, cam card say's .426, I've got about .428.

Here is a pic. with the vave at half lift. Seems a little off(leaning back) to me.

Your gaps are survivable.

If ya want it perfect. You will have to cut the stems to match height. Or get a new valve job. (not needed) (just depends on how anal you are)

It looks like you are on the right path.

Just keep it going. The first ones are the hardest. Then it gets faster. (NOT easier)

Here is a trick that Craig Downs taught me.

Grab yourself a stock pushrod (PS)

Cut it in half. (Hack saw or Lathe or arrow/pipe cutter)

Then thread the hollow end with the same thread as your rocker arm adjuster.
Then simply screw the half PS onto your adjusters. Place one on the intake and and one on the exhaust adjuster (the pair you are working on)

It will look like you just made the adjuster threaded section about 4 inches long.

Now with these extensions screwed onto the adjuster.
It is MUCH easier to visually see the alignment of the adjuster VS the stem angle as you look across the valve train.

It's kinda like trying trying to make a big wall plumb with a 2 inch level.
If you put a 6 foot level on the wall. You can stand back and really see the angles easily.

This a GREAT tool to see what the hell you are doing.

I can't thank Craig enough for this tip. (IMG:style_emoticons/default/KMA.gif)
It works very well and saves time.

This tool should be mandatory for a first timer. (as well as us old guys with shit for eyes)
As it SHOWS the stem / rocker angles in a way that you can get your HEAD AND EYES INVOLVED IN THE PROCESS WITHOUT HAVING TO CONSTANTLY SECOND GUESS WHAT YOU ARE REALLY SEEING.

By the way. While you are in there. Just for shits and grins. After you have set your GEO on one pair of Intakes and Exhaust valves.

Run the cam up to full lift. Check how much clearance you have for coil bind. Since I have no clue what you are using for springs. This is always a good practice. Coil bind kills parts... QUICK.

It's also a good time to find out if any valves are hitting pistons once the GEO is done on one cylinder.

If you are building a known combo. This will probably not be a problem.
Just thought you might like the technical exercise.

I dunno. Is there anything else we can help you with?

If we are lucky. Jake will pop in and take us all to school.

I reiterate. PM Craig Downs for more input. He is VERY good with this and he taught me a trick or 2 I that didn't know.
But he is kinda ugly and smells bad.... Thats just some of the shit you have to put up with dealing with Craig. (IMG:style_emoticons/default/chair.gif) (IMG:style_emoticons/default/agree.gif)

Cheers,
Clayton
