Brand:Chevrolet Country/Region of Manufacture:United States Manufacturer Part Number:10185040 ported for small cuin 321:comp eliminator made 745hp Warranty:No UPC:076783016996

Good condition set of bare splayed valve chevy heads and sheet metalintake.These heads have already proven themselves to make power 748 hp on a 321 comp eliminator engine. The orginaly came from nickens racing and the port was shaped and designed for a small cuin sbc,it had a sheet metal intake shaped like a victor jr with a 4150 top.Im selling these to go big block.the head  had 2.20 intake and 1.625 ex.I was build a 436 so in order to maximize the heads potential I had the out side of the intake runners built up with more aluminum so If we needed to raise the roof we could or widen the throat area for more csa and runner volume and shape. these heads can be used now you just need to mill or grind down the excess weld so the rockers will fit.Mike stark @ CFM porting has them now we were going for 930to 970 with the engine set up for nos .we were gonna use 2.230" with 50* intake seat and shrink ex to 1.60 with 55*seats these heads take around a 5.750" long 11/32valve.mid to low 400cfm is expected on intake and around 280s on ex.the intake comes with the linkage and rubber oring gaskets and dual dominator top it also has a baffle under it so you hook up a vacuum pump.I have a set of valve covers but I have to find them and sned them out when I do .I have the single 4150 victor style intake avalible if you just wanted to use these on a 360 or smaller engine , I believe with the dual dominators and a nice aggressive cam these heads could pull 810 to  820hp the way they sit if you look in the pic of the intake runner notice the shape how it contours very efficient heads. was going to soften the chambers for nitrous .I can have mike ship these to the winner or you can have him finish them up.He was charging me 1500 to port heads and intake and only a little to mill rockers and soften chambers .never got quote bit he does excellent work and at a hell of a price.I also have some splayed valve 1.5 rockers these and the valve covers and intake are in same place I just have to go get  the stuff.but whoever gets the heads will get first shot at the rockers and intake I will just give them the valve covers which I priced ne ones at 500$ or more. any questions plz ask if I can answer them ill call mike and get you a answer and whoever buys ill hook them up with mike . Thanks will not sell intake alone but will sell heads without intake. I will have to ship in 3 boxes.I have seen heads like these make 975 with 2 1050s and a cam around 284on in with .900 lift on 115
