I have a brand new set of Holley Heads P/N 300-552-1 for sale. I don't have the boxes for them, but they have been wrapped up in my shop for roughtly two years. I was planning on using them on my next engine build up, but since then I have gotten another set of cylinder heads that I am having a Winston Cup engine builder and his cylinder head guy give them their performance touch. Plust they have smaller combustion chambers for more combustion and that is what I really need. I looked them over the other day and some of the valve springs have started to get some surface rust. If you remove the springs you cna clean them up with some steel wool and give them a good coat of oil be good as new. I've had these heads on naturally aspirated 420 CID small block chevy engines making between 500-550 HP right out of the box.

Details about the heads:
Aluminum
20 deg Valve angle
Combustion Chamber size: 68cc If your engine is currently 8:1 with 76 cc heads your compression will increase to aroud. 8.7:1. If its 8.5:1 you'll be around 9.3:1. Depends on your deck and gasket thickness you choose.
Exhaust runner voume 68cc
Intake Runner volume 188 cc
Flow at .500" lift - I=223 cfm E=173 cfm
2.02 Stainless Intake Valve
1.60 Stainless Intake Valve
3/8" rocker studs
comes with Pushrod guide plates
Bronze Guides

If you use these heads you will want to purchase the correct pushrods, because the deck on these heads are not a think as the stock pieces so you will need a different push rod. Holley's p/n is 301-37 or if you can find 5/16" x 8.040" pushrods you will be set. If your using roller rocker arms you will need to determine your own length.

Summit is selling them for $1,129.95. I'll let these go for $600
