A1 Technologies L19 head studs :notgood:

The spring locators for springs like kiggly are a hair size smaller then the stock locators. So you won't have any issues installing your A1's. I just got lucky when I broke mine. I am going to shave my spring locator just a tad when I put it in. That way I will be able to pull the head if I need to.

I am using Manley valves and springs too. My shims are underneath the valve locator seat. Your photo shows a valve locator seat, not a shim. I too had a couple of the ARP nuts only just clear the spings. Nothing to get me rattled though. The head worked fine until the a pinhole leak occurred in the bowl on an exhaust port. The real reason I am posting to ask you where you got that valve spring compressor and how much did it cost?

The valve spring compressor is sick. I bought it at Euro Export, Inc. for $65. They shipped it super fast, and it fits PERFECT. This is my first time ever using one, and it was too easy.

I am running Crower S+R's and I did not have any issues with install of my A1's. I also got mine from MAP(thanks guys). So far they are holding plenty of boost.

I installed them and the head is bolted down. Everything worked fine the 2nd time around, I must have just caught that spring locator JUST right.

I just picked this piece up too. Did you do this with the head still on the car or did you have it off?

I did it with the head still on.
