Guy,

Hate to say this but it needs saying: solid roller lifters do not last 10K miles....

5K to 7K is usually the max, even with really good maintenance.

If you must have them, it's a really good idea to replace/rebuild them every 5K miles.

There's a new type of solid roller lifters that are advertised to run more miles; it would pay to find someone with actual experience with them before going that route.

There are some new-style Crane hydraulic roller lifters that are supposed to be OK to 8500 rpm if you need that. I haven't tried them.

I have run my old-style Crane hydraulic rollers 30K miles without incident so far.

When you are rebuilding the engine again, I'd recommend thinking about this change.

Just sayin'

Tom
