Billet Shovelheads...

Hey everyone, nice to be here.

I just wanted to put out the word that I've picked up where STD left off and have come out with the best shovel and pan heads on the market. I'd be happy to answer any questions or provide any imformation you'd like to know.



INTRODUCING...

SORENSEN PERFORMANCE?S BILLET HEADS FOR SHOVEL HEAD ENGINES



Available in 3.5, 3 5/8, 3 13/16 configuration.

Everything that you thought was bad about shovels you can forget. Easily run up to 11.1 compression on pump gas when properly installed.  Everything else pales in comparison.

Depending upon how they are set up they can easily flow up to 275cfm@28" at .650 lift with a 2.02 valve.

Valves are Av&v intakes and Ferra exhaust small stem valves with Evo Bronze Av&v guides.

These heads have an extremely high velocity small fast moving port. They will enjoy cams with 8 to 10  degrees overlap and high lift. We are currently dyno testing and working on specific cam profiles.

They have additional fin area around the entire head unlike the competitions and run 50f cooler! We have included a picture comparing our heads to the competitions cast heads you can clearly see how much additional fin area has been added and are drilled for decompressors for easier starting.



Heads are CNC ported!

The heads come complete with 2.02 x 1.710 valves, .650 lift Manley spring pack and titanium retainers, 1.780 raised port floor intake opening. The head is also set up that you can build an evo clamp style intake for it and toss the rubber bands!

The heads also feature a unique fast burn dual quench chamber and are so efficient when properly set up the engine will enjoy a 14.1 air/fuel ratio.

Valve angles have been moved to allow huge TDC lift.

Bolting these heads onto a 8.1 piston set up will increase your compression from .5 to 1 point of compression depending upon size of engine and stroke.

Every set of heads are hand blended before being sent out.

Initial testing has already seen 110hp on a 93" engine on pump gas.

Also available shovelhead conversion lifter blocks, hi flow backing plates, billet evo lifter blocks, billet shovel rockers, billet evo rockers, coming soon billet big bore cylinders and billet pan heads!
