Believe it or not, there is a huge difference between using a cylinder head "stud" and a cylinder head "bolt." Factory head "bolts" will eventually stretch and pull out of the cylinder head, leaving a not-so-wonderful opportunity for a blown head gasket, warped cylinder head or costly damage to the engine block.
You have two choices when re-installing a cylinder head. Use brand new cylinder head "bolts", see Part# 1024063 or install a new set of cylinder head "studs", see Part# 1024069. Cylinder head "studs" CAN be reused and allow the head to be evenly torqued down. In performance and high compression applications, it is recommended that you go to a cylinder head "stud" set up. For technical assistance, please call our tech department at (928) 855-6341.
NOTE: It is highly recommended that you DO NOT install used head "bolts."
