well, my motor guy got the motor done the other day and i was wondering if it was really necessary to retorque the headstuds on my ls/vtec after driving it for a few miles??? another engine builder that i know who has done many ls/vtecs says that he never does it and that there is no need to. The studs were torqued to 75 ft/lbs so it's pretty tight already. if there is anyone with experience in this area please chime in. Thanks
