No not mine. I already know how that is functioning!!

(Actually I really do. After my stroke, I was tested "up the kazoo".)

Snyder's offers two cast iron HC heads; the A-6010HC (5.5:1) and the A-6010HC6(6:1)

Question1:
The 6:1 head is only $10 more than the 5.5to1. My question is why would you not want the 6:1 head, which makes more consistent power over the model A's RPM range? Put another way, what is the down side to the 6:1 head?

Question2:
Are these cast iron HC heads a direct bolt on (without any mods other than using a model B gasket) replacements for the stock head?

Question3:
Are they machined to use the larger model A spark plugs, and can I use my Champion 3X plugs?
