Heavy parts kill everything. We have a certain LS7 head here with 144g intake valves! I won't use them. Everyone is giving good advice and like Shane says the ETP and heavy stuff needs more spring pressure to work right.

I like the Manleys and the K800 that Brian showed us too for their respective lift ranges.

Agreed.

Also, not sure why more people don't use the PSI CT1225's. They are a bit pricey but their low rate is perfect for high seat pressure without getting crazy over the nose.

If your running Ti intakes you should be able to run the 1521 no problem. I hear a lot of hype about these cts-v lifters but are they really that good? Seems like they cannot handle over 500lbs without bleeding down.

A lot of people are running cams so agreesive 500lbs is not enough to control the valves at high RPMs.

What lifters can handle the K-800's from Cam Motion on a TFS 235?

What about an LS7 lifter?

What about a Morel-people mentioned there a different ones-how do you know which one your getting? No link-bars.

TIA.

We have the reg normal Morels that use the OEM lifter cups if you want those.
