Brand new set of phase VI botie aluminum 23 degree cyllinder heads (Never ran) #14011049 that are completly assembled and ready to bolt on. These heads are fully CNC ported and polished, (full race) and have the Jesel .450 offset rocker arm set up, 1.50 Ratio. # in the rocker arm bridge is STN 20010. 2.08/1.60 Ferrera stainless valves with triple valve springs (isky9365's) aluminum bronze guides, Dart seats, 5 angle Valve job, Silverseal Polymer Seals and angle plugs. I had these heads built by a professional engine builder a few years back with the intention to build a 427-454 cubic inch small block but never followed through on the rest. They come with a flow chart and were flowed to .750 lift. They may require the use of offset lifters and have standard valve spacing. 55cc combustion chambers, and these heads have the standard intake port location so a standard intake will work on them. "D" exhaust ports. These heads would be killer for the right person and keep in mind that everything is NEW.... I am not in any position to trade for anything, sorry... Please E-Mail me for any questions you may have. If they do not sell, I will keep them! but for this price, how can you go wrong! COmpare them to the #'s on the 200cc and up heads, these are built to accomidate the RPM's! I have roughly 4500.00 invested including the price of the heads, I will sacrafice for $2,300.00 FIRM. Serious buyers only!
INFO from the catalog below:
SBC PH 6 Aluminum Bow Tie Bare Head. Price, 750.00 a piece.
Listed on page 51 of GMPP 1998 catalog. (Discontinued)
The Phase 6 aluminum Bow Tie cylinder head (casting P/N 14011049) is the product of years of testing and development. The Phase 6 head has the highest performance potential of any Chevrolet cylinder head with standard intake port locations. It features high-flow intake runners, high-efficiency 55cc combustion chambers, and D-shaped exhaust ports. Port wall sections are extra thick to allow extensive modifications, and there are no water passages under the valve spring pockets. The spring pads are machined to accommodate standard length valve stems. The valve seat inserts are machined for 2.02” intake valves and 1.60” exhausts. The angled spark plug holes are machined for both tapered seat and gasketed plugs. Phase 6 heads are recommended for maximum effort racing engines which require a standard intake port location.
Technical Notes: Pushrod guideplates P/N 14011051 and 3/4” head bolt washers P/N 10051155 must be used with Phase 6 heads. Intake manifold P/N 10051102 is recommended for single four-barrel applications.
