What's goin on guys, just had a quick question about the cylinder head on our blasters. I picked up a nice head for $12, I didn't need it but for the price and condition its in I figured why not. So far I painted it in high temp flat black and sanded the tops of the cooling fins ( yes I stole the idea from some people on here, it looked so sick I couldn't resist haha ). I was gonna lap the gasket mating surface down a little bit but I wanted to make sure it wasn't possibly done already. If anyone knows the stock height of the gasket mating surface id really appreciate it !
