Hey Cylinder heads guys- advice needed

Hahaha no ****. Like it would be too hard to change the casting number 1 digit for each. I think they just wanted to screw with poor suckers like me.
:soapbox:

Here's what I've always wondered. Why the HELL did they make a W2 for use with stock length valves? If you're runnin a W2 head, you're gonna be runnin a badass cam that requires badass sprAngs that will need longer valves. Never made any sense to me.
