Up for sale are a set of 2004 USDM STI heads modified with Ferrea 1mm oversized SS intake and exhaust valves, Supertech dual valvesprings, Supertech Titanium retainer kit, and are hand ported with a 4 angle valve job making them ready for 9,000 RPM. The heads DO NOT INCLUDE CAMS, but valves etc are installed. I will include the buckets from another STI head, but of course these will need to be carefully sized before installing with your choice of cams.
The heads have not been used installed since they were reworked. Please take into account the cost of the parts and services before making a reasonable offer. Basically with the cost of those nice parts and a head to work with, all the machining labor to cut for larger valves, porting, valve job, and assembly is free! I really don't want to sell....these along with the Kelford cams I recently sold were going to make for an awesome top end. Unfortunately, my project won't come together for a while and I've got an upcoming operation to fundraise for. Asking $1075 + shipping!!
