Hello all.

I have several sets of Evo 9 beehive springs and featherlight retainers I have been collecting from doing head-work here and there. These have been proven to 9000rpm (with Comp2's) on one customer build, and 780whp@42psi in another. Unless you are running some custom COMP cam with a ridiculous ramp rate or 50++psi, this is all the vale spring you will ever need.


Sets $80 shipped/insured/pay-paled to the lower 48. $75 if paying cash/money order, and $70 local pick up.

I can grab sets if your looking, but there is not real performance gain there. They are identical to most 1/2G valves (I say most, because some early OEM versions had a large, heave stem head) and contrary to popular belief, the EVo valves are nto significantly lighter than our junk.

They are just nice to use because the drop in, and are "clean" .:)

Paypal is tercelturbo@hotmail.com. This is also my home email. Please-shoot me an email and make sure to include your name, address you would like it mailed to, and paypal handle so I can keep track!

I'd be interested in a set of evo 8/9 springs and retainers. Got any sets left? I'd also be interested in set of evo 8/9 exhaust valves. Please let me know. Thanks for your time.

I have sets left. Paypal is listed here if you want me to get those out in the morning.

As for the exhaust valves, I am all out, but as I told some others Via PM, there is no real performance gain with them, as they feel negligibly lighter ( I will admit, IO have not scaled them), but the same diameter, and the stem shape is the same. Its externally exactly the same as most 1G valves (some older ones have a larger, more pronounced stem)
