SC-520™ Spread-Port SET:

Shaft mount, off-set rocker systems with wide intake off-sets / "Z" style intake rockers and narrow exhausts.  Examples include: Brodix Big Duke and SR-20, Dart Big Chief, Edelbrock Big Victor, Pro-filer Hitman, Reher Morrison 12 Degree as well as the Brodix Head Hunter with moved centerlines. 

The SC-520™ comes with two complete tools: the SC-500™ Intake tool plus the SC-501™ Exhaust tool for when speed counts. Doing a lot of springs or often, the SC-520™ set is the way to go to save time.

The intake shaft is slotted for centerlines of 1.625" to 2.695" and is 3.25" overall length. The exhaust base is slotted for centerlines of 1.40" to 1.70" and is 2.25" overall length. Both accommodate 5/16" bolts or studs. 

Also for Ford C460 intakes with T&D & Jesel rockers. Use the SC-200™ (not the SC-501™) for exhausts. We can make a SET similar to the SC-520™ if desired. Call us for details.

All LSM on head valve spring compressors have a tapered flange retainer housing that can fit springs as small as 0.800" up to 1.600"And they can easily and safely handle 1,000 pounds of seat pressure with our screw down method that will not spin back. Plus, you won't need an extra set of hands so you don't lose your keepers. No need to take off the pedestals - our compressors bolt right to the stands!
