With 42 x 37.5mm Stainless Steel Valves, CNC Porting, Dual Hi-Rev Springs, Chromoly Retainers, & SUPERGRIP™ Valve Locks. 90.5/92mm Bore.

All ULTRA MAG Plus Cylinder Heads feature full CNC Porting. The intake ports flow 120% more than stock VW cylinder heads. To handle the extra flow capabilities of the intake ports, the combustion chambers are also CNC machined for maximum power and flame travel. 

Spark plugs are secured in re-located 12mm spark plug bosses for increased strength and durability. The exhaust charge is accelerated through the CNC Machined exhaust ports. Avalaible here

Based on the same 044™ Castings as the rest of the 044™ line up, ULTRA MAGS have been taken to the highest level of performance with CNC porting.

Standard features include: 3 Angle Valve Job, 42 (or 44) x 37mm S/S valves, chromoly retainers, hardened valve locks, dual hi-rev valve springs, silicon bronze valve guides, nickel chromium alloy valve seats, and CNC Porting.

ULTRA MAG Plus Cylinder Heads (sometimes referred to as Oval Ports) are race ready and offer maximum HP potential for ultra high performance engines right out of the box.
 
If you have not seen CB CNC ported heads they really are something to behold, they take all the guess work out and the labour intensive porting work is all done. 

Chamber is 62cc's
