Those must be what you mean, seems like the whole she-bang for a great price. Doesnt say if the require the 1.85 length or not though.

it was a .210/.220 duration .510/.510 max lift compcam.
Your valve being shorter then recommended will not change the overall lift. It will compress the spring a little and raise the open spring pressure... but lower is max lift capabilities, and probably shorten it lifespan a little.
yes those are the ones i'm talkin about, its a complete drop in kit. works at stock install heightQuote:

^ he nailed it. If the specs on the springs said they are good for up to .600 lift @ 1.85 installed height, then at 1.75 installed height they would only be good to .500 lift before coil bind.Quote:

This is all interesting stuff. I've learned quite a bit about the dynamics of the valvetrain through this discussion. I'm concerned now that I'll hit coil bind because of the valves being too short. I'll need to take a measurement of my valve to be sure.
"You can use high ratio rockers if you like as long as the lift is no more then .590" @ the valve and the installed height is properly set." Wish they listed what the installed height is supposed to be. I'll be running 1.6's, and my cam won't be over 590 but the installed height could be off and ruin the whole set-up.
In the end though, for 125(including new seals), these springs can handle the cam better than what I have currently.
they install at stock height i'm pretty sure. They are made to just drop right in and go. If thats not how they work then my little cam would be coil binding the shit out of them :p
Anyways.... IIRC someone said when i was looking at springs for my new cam that i should pick a spring that has the capability to handle atleast .030 more lift then the cam and rockers actually create... ya know "just in case"
Got me thinking about it and remembered this: "You can use high ratio rockers if you like as long as the lift is no more then .590" @ the valve and the installed height is properly set."Quote:

well it depends on what the cam was spec'd for, if it was spec'd for 1.5 ratio rockers then you add 1.6 ratio rockers to it then you'll be at .604 lift and that is to much. If the cam was spec'd at .566 lift with 1.6 rockers then you will want 1.6 rockers.
Oh Ok I hadn't thought about it being all ready for 1.6's. Thanks
