has anyone here tried a custom comp grind in the tr224 pattern 224/224 .563/.563 112 LSA. the tr224 cam is pretty popular and i heard that the comp xe-r ramps are pretty aggressive along with the tr224, so if i got a custom grind they should perform the same, only reason im asking is because i get a comp discount through my friends speedshop. and also, does anyone know the idle characteristics with the tr224,
