these came installed on the heads that i bought, but im going a different route with a bigger spring. these have been mounted on the head but never used.
good to .600 lift, and fits the stock lt1 head without having to machine the seat.

*EDIT* i forgot to mention, they came with locks and retainers also, but i have no way of knowing what part # they are, im assuming they are the matching crane components. most likely the 10308-1 kit.

$110 shipped for the whole package sounds like a good deal.

 

The Crane kit for aluminum head LT-1s is the 10308-1, and it comes with
the 99893 springs. You can buy the kit for $150. The springs alone can
be had for $115.

Since you are not sure if the retainers and locks are the Crane parts from
the 10308-1 kit, how are you sure the springs are 99893s? Also, how are
you sure the springs are new and never run?

Anyway, if you are sure the springs are new 99893s, I'll offer $90 shipped
for the springs, retainers and locks.

 

thanks for the info, like i said, im not sure what locks/retainers are used, and i wasnt aware there was a kit, i just searched for previous sale posts of 99893's and looked at their prices for similar setups and it was higher, they probably had better locks/retainers.

im in no way trying to misrepresent anything, so i appreciate the help.
i adjusted price to be reasonable since i will assume i have the base kit.

the heads were done by jordan musser and the springs were installed when the heads were ported, he confirmed they were 99893s and that he never used them. he sold them to a customer, who ran out of money for a project and never used them, and then re-sold them to me, and i have not used them either.
they have a painted red stripe down the side, which shows no sign of being exposed to oil (which would happen if they were used right?).

 

Thanks for the additional info. I'm sure the springs are new based on
your explanation. Keep me in mind if you decide to let the stuff go for
$90. I'm going to pick up a couple of different valve spring setups and
play around. I have heard that the L98 spring seats work with the 99893s,
but I have not confirmed it myself.

Thanks for the quick response and send me a PM or email if you want to sell!
