aluminum head... lol

TIG welder bro....works wonders.

Mill the eyebrows. Cuts a bit of compression, but great for the flow.

i was already gona cut the eyebrows and do other crap... and id rather not end up warping the head for more un needed compression... these oppys dont like to much compression neither do the starters lol

You add weld in between the fins, so you can mill meat out of the head, this reduces compression but does wonders for the flow. There are a few threads on 4 cycle that deal with this.
