- boss internals, local machine shop balance rotating assembly
- aftermarket internals, local machine shop build / balance
- aftermarket short-block (which vendor)
- L&M seems like you should have sleeves too by the time you pay? (AKA) kinda expensive.
- modular head shop has a good looking site for parts, and short-block, but have heard horror stories
- local machinist is good, but afraid of the wait with everything apart for too long, but price-point is good, and no extra lump of Coyote short-block sitting around taking up space.
