Stage 2 Cylinder heads 25500031 castings. Heads were from Ricardo LaCosta's TTS2 WH1 and have run 8.20's@168 with old school 62 turbos @3300#. The heads are an excellent turbo head or head for a street car. They were never on a roundy round car and where originally ported for Ricardo from new castings to be used on a turbo motor. They have never been damaged repair or all hogged out like some of the Busch stuff.
They have excellent flow numbers and I have the flow sheets. Intake to exhaust ratio is 72%. The chambers are 42.4cc. Valves are 2.02/1.60 stainless steel, titanium retainers etc. Springs have very little use and are for a solid roller but I don't have the specs as the machine shop forgot to check them when they had the heads apart. The springs are matched for the cam I have listed below so they are going to be pretty stout. Rockers are T&D 1.65/1.60 ratio and in excellent shape. Valve covers are in excellent shape. One exhaust valve seal is spit and needs replaced but heads are ready to run otherwise. Machine shop said valve job still looked good but he feels he could get a little more out of the intake changing the back cut on the valve seat. Head surface is cut for reciever groove for o-ringed block and copper head gaskets. $950
