Shorter Valve Seals?

I’ve been using cam motion kit vsk915326,

for eagle&6.4 there’s room up to 625 lift, over that lift,mill the guides another .060 to .080 and you’re good

pre-eagle, 6.1 top out around .580&.600 respectively, what ever you lift above those # + . 04 for safety.. .623 lift 6.1s would be a min . .065 to start.

reality is .100 is the safe bet.

comp cams positive stop seals for 09+ are also good, again mill roughly.10 off the top to start

I dropped my heads off at the shop on Monday and told them to knock .100 off the guides, glad to get confirmation on it though. the seals I am going with are the comp cams p/n 516, do you have any suggestions on spring locators? ideally I would like to find a set that are .040 thick so I could use my existing shims.

Anything .660 to .720 Id will work, there’s a few out there as thin as .045, . Try Ferrea there $3.40ish a piece

I checked out the ferrea locators, aren't they too big for the guide diameter?

I picked up a set and the photo on the website was definitely a misrepresentation, I didn't know they were the top hat style seal/locator. now I have two sets because they're exactly what I had on my motor already. I emailed comp cams to see if they have anything that will work, my springs are 1.310" OD and .890" ID with the standard .525" guide diameter, and (locator plus shim) I need .060" under the exhaust spring and .100" under the intake. they've got a few that are very close, I'm hoping they get back to me soon.

well, rather than trying to chase down parts I decided to just go with the Cam Motion .660" kit instead, 350 bucks and it comes with everything. Cam Motion kit
