Chris,
OK, that's good news.....if it was me I would still make and install internal "JWE" spacers. The needed remaining play in the chain is only for differential expansion of the engine relative to the chain,... so you don't need much after the engine is installed and bolted together. The wide range of travel is to accomodate the large variances in engine parts and head fly cuts/etc. Remember that some racers use solid tensioners. Don't take my word as for sure just my thoughts on the subject. If you have good working hydraulic tensioners you will likely be fine for a long time to come. Remember I come from the if it ain't broke fix it camp.
