Description:

With Evo cy heads in rebuildable condition hard to find.   Been using the Kia/Hyundai cylinder heads. Many write ups on Evom.  First used one in 2010 on a 2.3. Then regularly on 4g64 builds.  This is a core. As always replace guides. Super tech bronze are $100 a set.  Needs one seat.   BC single spring sets are $125.  Many diff valve sets $200-300.  Comes with Valvecover. Thermostat housing assembly and cam sensor.  The ports at the valves are cast and machined well on these heads.  Have tested them zero porting and ported on the dyno.  Haven’t seen many cores in the yards in a few years.  Getting difficult to find.  Can build a cy head for a fraction the cost of using an Evo 8 core. Have two other cores also.  Can message me with questions.  702-741-6987.
