Head bolt block thread
Read the whole thread " ARP STUD INSTALL BLOCK THREAD FAILURE " and so no mention of another possible cause. ARP now uses the hex on top for finger tight installation. Is it possible PO did not install some full depth due to friction? Seeing how much stud protrudes thru nut before torquing...- PROFG
