351w heads
I have a pair of 351w heads from a 72 galaxy. Does anyone know the chamber size? Intake and exhaust valve size? What the compression ratio would be with flat top pistons with standard (OE) rods and crankshaft? They are DOOE heads. Also, the rockers are not stamped steel, are they cast steel or cast iron? Fixing to build back-up motor just in case primary one blows. Knock on wood. Thanks

It says they are 60 cc. so with a flat top piston I think they make about 10.7-1 or something like that.
I have the C90e heads on my 69 351W. I home ported them myself. I know they arn't fancy high doller aluminum AFR's or something like that but I've always heard they are as good as the famous GT-40's when ported. They do have the biggest ports and valves than the later modle heads. I'm happy with mine
