MACHINING OF THE BLOCK AND HEADS REQUIRED
Benefits:
- 25% stronger than 625+ studs and 40% stronger than 11mm ARP 2000\'s
- 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
- same kit price compared to 625+ kits (requires additional block and head machining to use)
- 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.
