volume thus increasing compression ratio.
The thing is another poster said that putting on a stock 913
head will boost performance as would bolting on a stock
848 head.
So would those looking to hop up their engine
be just fine going with a 913 head being people charge a
premium for an 848 head?

So what is the same or different between those two heads?
