Slant six head

I used stock 318 valves in my head. I did that for a couple of reasons. Primarily because at the time, no one had the obligatory 1.70 and 1.44 over sized slant 6 valves. Also, because the 318 valves are bigger. lol If you do that, you will need to contact Mike at @B3 Racing engines to get your rocker shaft relocated, as the 318 valves are .300" longer then the slant 6 valves and require relocating the rocker shaft to correct geometry. There are other options that don't require "all that", but in my situation, that was the quickest and easiest thing so I did it. That's just a decision you'll have to make.
