i have a set of diamond pistons for my 445 fe stroker build part number 42021,i was just informed by my engine builder that the ring land grooves were not cut deep enough? has any one ever heard of this?. i sent an email to diamond i just want to find out to make sure he is not trying to nickle and dime me.
hopefully keith craft or barry r could chime in on this.
