as for the spare head.

going to look at drilling and tapping for 14mm x 1.25 spark plugs. have bigger range of plugs I can use and then the helicoil doesn't matter. I believe I already have this tap in my sets. of course all I have is a 14x1.5. just need to drill to 1/2" or 12.8mm. then tap.

head is not HC head. it has been decked already, but I can tell it has deeper bowls then the one on my car now. which means lower compression. may look at decking it further so compression is raised, especially with today's pump gas.

once I get the old head off i'll beable to tell the bowl size difference and get a machine shop to match deck height since I know the valves clear on the old head.
