I'm testing a few different combinations using the Sidewinder heads. First up was a back to back with a mild hydraulic cam versus 915 heads.
I'm testing them in ported form right now, with a couple different solid camshaft. I'll be posting results in the next day or so.
But I can say, so far so good! They are looking like a great option.
