Regarding the Hemi head design that Cameron is not a fan of, but Dodge sure has gotten a lot of mileage out of on their truck ads...... I was looking at some Harley heads at NRHS Performance just last week, and noticed the nice "bathtub" combustion chamber of the Buells and larger motors. It got me thinking; what if I welded in the sides of my combustion chambers and milled a new combustion chamber with more squish area and higher compression? Nitro is also an interesting option, when I'm sure I'm done with the N.A. version, as I'm not sure the old girl could handle a 30% boost in hp.
