Looking for a good set of 350 heads to fit a 1986 350 4 bolt main. Would like to find them within a 50 mile radius of Albany GA.

 

I have a set of 305 heads with a 416 casting, 58cc chamber i believe. Great condition, complete.

Did you still need a set of heads? I have a set of 081 castings and Im in Warner Robins.

 

no sir bought a set of 416 heads

 

Are you putting those 416's right on to your 350? Or are you going to do some work to them first? I am wondering how the 1.84 / 1.50 valves will perform in a 350.
I have a set of 416's from my old 305 that I want to use on my 350, and want to know if I should change the valves to 1.94 / 1.6 first.

 

these heads have been ported and bowl blended.

 

If you put 416s on your engine, it would be wise to do some home porting, bowl blending, and increase the size of the valves to 1.94/1.6. Also, you can buy a $20 tool from summit racing to take out the pressed in studs, and line up a tap for the screw-in type (worth more hp in terms of higher lift).
