Here are some pics of my 15° W2 heads for a 48° lifter bore block.
I'm using an early R1 48° block. Going to be a nice little 360, all iron I guess to be different
Flow #'s to follow.
I think the 15° valve angle would work better if the port was raised more. But they work good enough for what I want out of the engine.

Chamber will be 48cc when finished.
