I'll have to agree with this statement.If dyno power is the only consideration, .. canted valve to some degree, .. and in some combinations it's not always a large difference.
However, sometimes an in-line head is proper for the application. Cylinder heads, .. port cross section, valve cant, delivery into the
chamber, wet flow, velocity profile, .. all of this stuff gives a head a "personality".
You can have two engines make identical power on the dyno and "race" VERY different on the track.
like so many other discussions on YB where it's attempted to make things black and white, ..
it's just not that simple.
This does not answer the question in any capacity and if you can't add anything please don't respond, it's counter productive.canted head ? please-
spend money on getting the car to work and leave the canted selling stuff to head porters that know fuck all in order to fool you
