Stock lifters are good to about 6500. Above that they tend to disintegrate and CC lifters should be used.

While I don't really recommend for people to change their cam and keep all those stock parts, it can be done with good reliability. The only reason we did this is because the car was fairly low miles (I don't remember exact miles, somewhere in the 25k range) so the parts were pretty new. On an older car with more miles I'd definately replace most of that stuff.

The only time a stock lifter will destroy itself is when you cant hold the oil pressure. The comp. cam lifters will actually destroy themselves with or without oil. Intense knows this, but selling a set of lifters is ~175 and and oil pressure kit is ~30. I was told this from an Intense affiliate!
ZZP still runs stock lifters shifting at 7k rpm.
I got a set of comp cam lifters somebody can have for $75 shipped. I WONT run them.

Assuming it IS true, what solution do you suggest?
The reason I ask this is that we have a few cars running this setup problem-free here.

Back to what I was asking..... It would be a good idea to have CC lifters if I'm going to be shifting @ 6400 with the Xp? & a single rollermaster timing chain would work well too? Aside from getting these parts to replace stock(high mileage) componets, the CC lifters are a improvement over OEM?

The CC lifters hold together better at higher RPM so if you plan on spinning the motor past 6500 in the future you may want to go ahead and put those in now.

I'm sorry I'm not going to reveal who told me.
There are a couple posts/threads about CC'* having problems on clubgp.
I'm NOT saying every comp cam lifter will do that, they are just more prone. IMHO
I have seen 2 cracked stockers and one calapse (NO oil pressure) lost the engine also.
Get an oil pressure kit and run stockers, you'll be fine. unless somebody really wants to buy my Comp cam lifters-lol.

An OEM roller lifter works great in high RPM applications when they are modified.
I always recommend Sherman Products for having hydraulic type lifters modified for high RPM use. They modify hydraulic lifters for FAST, NHRA and IHRA Stock Eliminator class cars. They rework OEM GM hydraulic roller lifters for the LT-1 and LS-1 engines. They can be reached at:
