Thanks for reading through that! I genuinely appreciate when guys read stuff I write about my junk. Makes it all worthwhile.
And yeah, the more I think about those heads, the better they seem. To me, it's somewhat inefficient to have a race style head (W2) that leaves horsepower on the table. Obviously W2s have their place. But why bother with those when you can have a conventional replacement type head make similar power?
Or, I could just fix the valve and bolt the head back on. That would be the most logical and cost-effective thing to do. But where's the excitement in that? Fix stuff? Bah!
