sorry everyone been busy lately and have not had much time for the truck.
Thanks wyoming4x4 just read your post again today and will try that I assume the valve retainer is the washer like thing around the valve tip? I put the stock pushrod back in the number one cylinder and rotated by hand pushrod was really sloppy and never got good compresion out of that piston a friend suggested the pushrod may be to short to open the valve enough to get compression, is that possible? Gonna try the sharpie thing.

I'm no whizz so don't quote me, but shouldn't compression be tested when both valves are closed???? Just before TDC? I would think that valve length wouldn't have much to do with compression unless they are too long and then opening prematurely? which would reduce compression readings

Corytcline is this an engine that has been rebuilt but not started?
If so that could account for the play in your pushrod because there is no oil in your lifter. Some people recommend that you place the lifter in oil and depress the plunger a couple of times until you see no more air bubbles come out of it.

Okay, your stock pushrod should be 6.881". It is obviously not correct. Your problem is not simple because of the variables. You have Chevy valves which are shorter than stock ford valves. This will make you need a longer pushrod than stock. However you have a rebuilt engine that may or may not have had the heads shaved, which would require a shorter pushrod. You're not sure if your 7.1" measurement is accurate. Your solution may be as simple as shimming the pedestal rockers if your 7.1" pushrod is close. Or you may have to get a shorter pushrod, there are too variables for an easy answer.

$1200 for the heads? Yeah they saw you coming.
The shims go under the sled assembly. Here's a video I found YouTube - ‪Valve lash adjustment on a 5.0L with pedestal rockers‬‏

thanks for all of your info yes they saw me coming on the heads my cousin did what he claimed to be 850.oo worth said he ruined two sets before he got it right guesse that was my fault because I paid for them then when I got them back still had to take them to another machine shop to get the springs and valves and all put on cost me another 350.00. I got five long years and over five grand in this thing if it fails at start up I'm gonna cry
