The J&Es are an order of magnitude more difficult to deal with then the Mahle/KS ones. If it is a race engine, rebuilds may be on the order of every five or ten years depending. A stock class 3.0 will go a long time shifting below 7,000 RPM. A 12:1 Compression modified 3.0 shifted at 8,000 RPM or maybe 8.5 or 9 is going to have to be gone through a lot more often.
