I'm selling my PRC stage 2.5 5.3's on my '99 Z28 to try out a set of our new ported Dart castings. These heads feature the stainless 2.04"/1.575" stainless steel valves and the PRC dual valve spring kit with titanium retainers rated up to .660" lift. The heads were completely hand-finished and flowed 306 cfm @ .600" lift! FYI, they have been shaved .055". This will net right at 12:1 CR on a stock short-block. Needless to say, if you are going to run a large cam valve reliefs will be required! They have been on my car for right at three months. FYI, my stock short-block made 407 RWHP through a Powerglide with a 5,400 stall, a Moser 12-bolt with 4.30's, and 28" Hoosier slicks with these heads!

I'm looking to get $1,000 shipped for the heads. I would sell them bare if anyone is interested. Feel free to e-mail me at trevor@texas-speed.com if you are interested.
