Anyone know the chamber size of these heads
I know these are nothing special. Both are 4071051 casting numbers. Both say P3 on the top. Both have a 9 and the same dial casting mark. This is every casting mark we can find.
I know these are nothing special. Just wondering about chamber size. Multiple searches on multiple sites did not return any results other than the same lixst of casting numbers on every site. Also seems like there were two versions of that head with different valve sizes. But I see no date code anywhere.
