Aftermarket Lifter Durability?
Greetings!
We are doing an upgrade to our 416 CI powerplant that uses a mild Cam Motion cam, Johnson 2110K (Katech) lifters and fairly firm PSI 1516 springs. We've only got ~10K miles on the combination. Any experience on when to send the lifters in for a refresh? Previously in a 96 LT4 combination (Gen II) I hit ~50K on OEM lifters, Comp Cams roller rockers, fresh beehive springs and healthy GM 847 roller cam - at which point I mushroomed a valve tip. Comp Cam pointed to race engine parts - don't expect OEM reliability. Just curious what people expect. Thanks.

If everything is setup correctly It should need valve springs replaced before lifters.

Valve springs every 25-30k miles to be safe.
We typically don't change the lifters unless something else in the engine came apart running debris through them. |

Thanks, gents. We will leave the lifters alone and swap the springs since it is convenient.
