| we dont say ntn
we know the xr100 heads dont have bearings ,,,thats usually the problem the oil gets low an wipes out the head
and hows the duration ?
most custom performance cams for use across the board to the public use additional duration to increase performance and not create valve clearence issues
did you actually have both stock and tb degreed ? or just use a caliper
we can get your stocker re-ground at crowerpower if your just after increased lift
