Cnc Ported L92 Heads
Mine are the TEA Stage 1, they are nicely done and the ports could flow small animals and birds thru them, it's just all the bolt holes are opened up and I'm trying to figure out a good way to seal them.
I'll have to try using that again. I was thinking about getting fancy on the Valve Cover ones since that rubber grommet is on the top and that aluminum spacer goes to the bottom.
I have this CNC Machine in Shop class... machine in a groove for an O-Ring and seal that one..
