Big Valve X Heads on Low Comp 72 340
I had some 2.02 valves put in a J head years ago. Same casting? Yes, but my machinist didn’t do the work the X head came with. I’m taking my J heads I’ve been reworking after reading and watching DV to get a proper throat cut. Here are three pictures; two of the stock X head and J with the half done 2.02 install. The X has a side cut to unshroud the valve and a cut down into the bowl. Most of the green dyed area on the J needs to come out. I’m giving the J heads an overall job to best of my ability. I’m saving the X head as a fallback if I goof it up.
