Wow I’ll have to see which one he gets. Do yourself a big favor and watch which valve coves you use, especially on the intake you got. I had oil leaks that took me awhile to find from the valve covers sitting on the raised intake runners. It looks like it could be even worse with the efi bosses. I now use valve cover spacers on most of these builds but they create another issue. They need clearances for pushrods. It never ends. Lol
