CB Performance 044 CNC Ultra Mag Plus cylinder heads cut for 90.5/92mm barrels and pistons. With 44mm Inlet and 37.5mm Exhaust valves.

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.

Based on the same ''ALL NEW FOR 2017'' 044™ Castings as the rest of the 044™ line up, ULTRA MAGS have been taken to the highest level of performance with 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! We do it all, just bolt 'em on!
