The exhaust side is virtually the same work, so the exhaust side has been flowed before.

The intake side I've not as of yet flowed in this configuration.... but as you can see below, much of what I do is the same. This head was a little conservative, but not extremely so....



Amazing what isn't seen...

A great deal... but its all there. From the top view you miss out on #1, and much of #3 but #2 and 4 are quite evident.

Since this is a California head I've left the swirl generators, but managed to adjust their shapes to something a bit more uniform, one needs a bit more work - does anyone know wtf I'm talking about :lol:
