So I have that figured out, I have another small problem, reassembling the heads and I had a case of the flying valve keepers, one keeper went on the floor some where, the other went accross the engine and into the intake port, so no problem just fish it out with a magnet, 
damn the intake valve was open. straight shot right thru into the cylinder. I have another set of heads with patriot golds on them but the keepers are different, Will gm keepers work / or do I have to call afr and order them? Will any of these work? http://www.summitracing.com/search/?...0keepers&dds=1 I found some gm keepers and they fit.

You need an AFR keeper. Call AFR this morning, if they throw a set in the mail you will probably get it in two days.
Can't you just fish the original one out of the spark plug hole? If the motor is on a stand can you rotate the motor and see if gravity will retrieve it? If not, you can slowly rotate the motor to bring that cylinder near the top and go into the spark plug hole with a magnet.

Vettenuts....
The "authority" on YT wipe pattern and geometry!!....LOL
Nice work guys....Looks like Bob has got you all buttered up and AFR has some keepers on the way!
The new wipe pattern and pushrod preload should work out great....the devil is in the details and all these details always add up to a better and stronger running engine when the smoke clears!

Hey Spraky and Bob,
I have almost exactly the same setup as you to. Just curious what your final pushrod length was. I want to take a stab at a size to order before I check just to see if I can hit it on the head.
With 7.400s I had about a full turn with no spaces and zero last with one of the supplied spaces. That makes me think that if I need two spacers I need +.050 + preload. I think that gets me closer to 7.500. If I do a .125 spacer like you guys, I'll need more pushrod.
Just curious on what you ended up with.
Thanks
Lance

Well thanks gentlemen! Maybe you can help me with this post.
https://ls1tech.com/forums/generatio...-question.html
These "street" Morel lifters seem to want more preload. I have them at .050+ and they are noisy. Even at that preload there was still alot of plunger left. I'm wondering if the street lifters want a different preload than the racing morels...

Hey Bob,
I talked with Chris. Thanks for the tip. Its not often you get the chance to talk to a guy like that. My only regret is meeting him late in my recent build. Thanks Chris!
Anyways, He said that the plunger depth on all of the morels is .140. He also said that they will quiet down after a few hundred miles. I'm going to give it some time and see if they quiet down before I readjust my Swipe.
Thanks again.
DOA

First, are you using the Morels to check wipe? If so, then the wipe will not be correct.
Second, you need more shim. You are too far to the intake side. Try taking one set of rockers and doubling the shims to see how it lays out. You can do much better then that.
Third, you have too much preload for a set of Morel lifters. 0.050" is the maximum you should run and I wouldn't rely on counting turns to get the preload. The Morels need 0.030" - 0.050" of preload and you need to be accurate.
First things first, get the wipe pattern correct. For background, with the 1.7 Yella Terra's on my AFR 205's, I needed 0.125" shims to set up the wipe pattern. Here is a link to how I set mine up: Link

I have been told every preload under the sun. I am just now doing my LS2 Engine with LS3 heads, Morel/Howards Cam 4708 lifters, Lingenfelter GT11 .631/.644 lift cam ,Yella Terra rocker arms.
I just last night did a Comp Cam pushrod checker to order pushrods for .045" preload. You sound like someone who has done a few engine set ups. Thanks

Here's the issue. Unless you are using a check spring, the plunger of the lifter will depress when you check the wipe pattern and will provide inaccurate information. You need to check with a different method.
Also, the pushrod length of 7.350 is gauge length. If you measure it from end to end it will be approximately 0.017" longer. That measurement is overall length.
