For sale is a one time used set of ARP chromoly head studs part number 234-4301. All are in excellent shape with no damaged threads or problems. These were used in an engine which had seen dyno time only for approx 1 year that had no engine failures or problems. Engine was taken apart to be sold in pieces since I'm switching to an LS based platform. Please see my feedback for other hot rod parts sold and feel free to ask questions. Thanks for looking!
