Flathead 6 valve to head clearence - 06/13/03 12:03 AM
Hi
I am finalizing my 218 CID '54 Plymouth engine. Cam is reground by Edgy,260° duration, .410" lift.
The cylinder head was cut .060" this time. Of course, its history is unknown.
I put clay on the valve heads, installed the head as a test,and rolled the engine over without a head gasket.
The clay is really thin in some spots; you can see the color of the valves through it, almost nil.
Should I wimp out and use a stock head, or rely on the thickness of a torqued head gasket to provide ample clearence?
