Outfront Motorsports Pro Series 1-2" Head Studs for EJ and FA 625+

Benefits:

• Reduced shank diameter (allows for no head gasket modifying)
• More thread engagement in block over 11mm studs
• Uses stock alignment pins without modifying case or heads
• Over 200ft/lbs tested for stud "pull-out" in block
• Custom large diameter hardened washers to prevent embedding into head under heavy torque values and HP levels
• Note, block machining can be done with shortblock assembled for an additional $100 fee. Bare cases are preferred.
