ALL NEW MODMAX STAGE 1 PORTED PI CYLINDER HEAD PAIR
If you are looking to upgrade your 4.6 or 5.4 SOHC 2V engine, these heads will add power and reliability! We start with PI cylinder head cores, cleaning, surfacing and then installing bronze valve guides and our ModMax stainless steel OEM sized intake and exhaust valves. The heads are fully ported and polished to our STAGE 1 hand porting specs. A competition valve job is done, guides sized and then professionally assembled with our ModMax .550" lift valve spring kit with chrome moly retainers. Viton valve seals are used for high temperatures.
PI WINDSOR APPLICATIONS - These can be used in place of Romeo heads as long as you use Windsor valve covers due to the different valve cover bolt patterns. Otherwise they are interchangeable.
NO CAMS, ROCKER ARMS, OR LIFTERS ARE INCLUDED in these assembled heads.
