HI Mike
when you get your replacement head just check the hight with the ones you have now, and if necessary you may have to fly cut your cylinder heads or the replacement to match and then adjust the cylinder base gaskets on that side to match the C/R back to STD. other wise if you assemble and not check the heads, the cambox could not sit correct on the heads, making the cam bind/tight in the cam bearings.
