The 8V is remarkably sensitive to even small changes in valve lash. Dont worry whether they are two thou larger or smaller, it won’t make any difference to reliability or cause any damage but if you’re running the stock map I would suggest clearing the trims after changing from one to the other.
If you’re running an aftermarket OL map check with the author to find out what settings they recommend. Just as a reminder to anyone running one of Mark’s maps, all the ones for the 8V’s are built for four and six thou, (0.1 & 0.15mm) for the reasons he states above.
