Pro Cylinder Head Set
At long last, we can introduce our performance cylinder head set for the 3.4L V6
(5VZ-FE), this is an awesome way to breathe new life into your 5VZ! We start with a brand new set of bare heads and our cylinder head experts port and flow test here on site to get a ton of potential out of your engine. We install stock sized lighter weight stainless steel exhaust and intake valves, the head is then fitted with LC Engineering exclusive Street Performer valve springs.
These springs provide a higher spring pressure along with a smaller diameter wire to allow the use of a higher lift cam without any coil bind issues. The valve train is finished off with Viton valve seals, hardened keepers, new Street Performer retainers. No longer will you need to bother with trying to get a set of old heads machined flat to keep from blowing head gaskets!
LC Engineering also offers our exclusive head stud set (Part #:
1024070) and our MLS head gaskets (Part #: 1024040).
NOTE: You will re-use your cams and buckets.
