Fins on back of Valve & Fins pre TB

FYI I been looking into those ZZP alloy ecotec heads, they are stated to have intake port volume of 148cc.

Looked everywhere for the figures for stock heads with no avail so I cc'd them myself.

120cc exactly for the late ecotec heads with factory larger intake valves. So I'm thinking those alloy heads that are claimed to have "small ports" are way big for NA.

Abbott race heads are right when he told me they are way big and only good for big boost. 28cc is a huge difference

The ZZP alloy heads are for L67 anyway Aren't they. I had a set which I sold that had injector ports, which means blown.

Ah yes, right you are.

while looking at the scrap pile at home I notice the ford log manifold.

there is what one looks like.



I checked, the port spacing is virtually the same as ecotec. Sooo... thinking cut one of these in half and you have 2 individual plenum and runners you can use to experiment on the v6.

Thats not my one, I was just too lazy to upload my own pic so I just googled it.
