fully ported, came off the #4 car (Morgan McClure Racing). heads like this from the WC cars (non restrictor plate heads) typically flow 370-400cfm on the intake side without any further work. with more work they can flow 420+ cfm and make 950hp naturally aspirated on a small block. they will bolt right onto a standard SBC block, just require offset lifters and SB2.2 specific headers (or custom headers)

includes heads, lower intake (lifter valley cover), top of the line T&D shafts, ARP stud/bolt kit, cast aluminum covers with valvespring oilers, and an extra set of springs and ti retainers. i lost the specs on them, so i am selling them rather cheap with that in mind. might get around to having a shap spec them out later if they dont sell. what i remember:

289cc intake runners
2.18/1.625 titanium valves
1.85in, 1.75ex rocker ratio
isky tool room springs
52cc chambers (will measure that to double check)

$2500+ shipping for it all

wow, that's some mean lookin' top end. Hopefully I can find a deal like this next year (when I have the funds to finish my stroker).

Just to be clear, all SB2.2 heads use 11º by 4º intake valves and 8º exhaust valves right? I'm assuming 23* or 18* pistons wouldn't cut it?

 

yes, SB2.2's have an 11* intake valve angle (SB2= 12*) with them canted 4* towards the center of the cylinder to help unshroud the valve, and the pistons must be SB2.2 specific. also forgot the camshaft must be SB2.2 specific as well since the intake and exhaust valves swap places on the outside cylinders compared to a normal SBC.
