@Mike Beck hurry with the build thread so we can get some super exciting car content šŸ¤£

@Raidmagic what's been going on with your build?

@Briansshop how many are you building at once right now and where are they at?

@Steve439 I have never seen any of your projects that I can recall, is that because of the Metadata in the photos and you work at a pizza factory?

I've been on vacation. Hiked to the bottom of the Grand Canyon and back up along with some other things. Now that I'm home I'm gonna order my Terminator X and get back at it. I'll update in the what did you do to your car thread

Here are a few shots. Grand Canyon from the bottom. My daughter on a rest at about 5 am. We started our hike out at midnight. Some shots from Antelop Canyon. That was worth the trip alone.

I'm thinking about making a detailed thread about the trip. I took a bunch of pics.

The stars were incredible at the canyon. Antelope canyon was awesome to see in person. Did you hit Winslow AZ while you were there?

These are -0.050. Why? The guy at PAC told me the retainer I am using with their springs are +0.050 by design. I find that strange, I would have thought all retainers are made neutral, but they are not. So he had me get this lock to bring the installed height back to what I wanted. If I bought this retainer and +0.050 locks I would have had the installed height for their spring that I wanted without buying new valves that are +0.100 longer. Since I wanted new valves anyway it didn't matter, just wanted all the parts to play well together.

Nice but you were to position them the same as fox pics, lol
Crane had different keeper and retainer combos but comp seemed to be one only.
 
What kind of variances is acceptable with installed heights on the springs?

Not a ton of responses, but I've read .010

Valve spring installed height questions?

How much variance is acceptable between installed heights? Just pulled springs off of a set of heads to take the inner springs out for cam break in. While doing this I ck'd installed heights and have over .020 between valves. Aluminum heads and they used a spring seat that locates on the boss...

If you want to spend the time I'd think getting the pressures equal is more important.
It's probably pretty difficult since you're limited by the shims available unless you grind your own...

I get all mine pretty near the same but I probably had more shim space to juggle shims around in than you. Try finding thicker and thinner shims of the "same" size.
Also, if my installed height is 1.90 I will shoot for 1.89-1.895
 
So far I've seen 1.788 up to 1.815

However I made some adjustments and got the 1.815 to 1.801"
 
That is a pretty large swing with brand new stuff. All that really matters is the spring pressure. Springs can vary a decent amount, especially cheaper stuff.

If you have an on-bench tester you could check the springs and then find out what height they should be installed at. But that is a long and tedious process and for this type of application not needed.
 
Oh and for the record. The fucking oil pan leaks in the corner. Just as I fucking expected. After dumping 3 quarts into the valley and distributor hole.

Dam. Looked to be a nice thick flange. It's not bulged between the two bolts is it?
Was that with a thin layer of silicone ?
