    We measured the clearance from the seat of the spring to the top of the valve guide shoulder. It was just over 22 mm. Add the seal which is about 4 mm. The spring compressed 10 mm to become about 32 mm. The retainer is 9 mm thick. Therefore when the spring is compressed, the retainer is sitting at 23 mm high. They are interfering. I need about 3-4 more mm of clearance.

    If I use my old retainers, with 7.00" pushrods, the retainer should clear the valve guide. Can I do that? Or would I need the valve guides machined?

    I measured pushrod travel, and I'm getting very close to the VS cam lift specs. So thats good news. However, I noticed my valve springs are all around 1.6" installed height. Why would they be lower than 1.8"?

    I think you found your problem. Let us know how it works out when you get them swapped around.

    Whoa, what, the keeper is upside down? I didn't even know that was possible. They are tapered and the smaller end goes into the retainer.

    Stock spring install height is ~1.72X"
    With modded/LS retainers it's ~1.78~
    Once you have the heads machined you can achieve 1.800"

    Glad you found it.. Thanks for teaching us something new and no..you want to use 7.050 aka stock length rods.
    I drink..so consider that when reading my posts.
