My experience is strip the short block ...seriously
the one my customer ordered was junk , the cam was one tooth out , the cam would not rotate due to locktite in the rear brg , the brgs were dry , no prelube or oil at all , they had installed lighter pistons on the stock crank & the engine shook so hard at 3000 rpm the dash was bouncing about 2" inside the car . we had to completely rebuild & balance the engine + to add insult to injury the cam failed during break in so we had to strip it yet again to clean the engine & install a new cam
