from another forum Wrote:Hey Dan, what is making you settle on 33mm exhaust port opening? I have some software telling me that 34 or even 35mm is ideal for an aggressive 20V build. I would think a race head would want at least that much exhaust port?

oldeskewltoy Wrote:In this case....I'm going on how much material I've seen removed by Loynings,

Somewhat more to the point..... What shape is the exhaust port in your software, not the opening, but the port itself? Are your ports "Y" shaped? Or "V" shaped?

[Image: AEU86 AE86 - ]

Imagine if you will you have sliced the head in half. The 2 halves are lower and upper. The "Y" you see above is the shape of a standard 4AGE port as viewed from above. The "V" shape is more of what I do..... I change the taper - photo is not exact, but shows the essence of what I do on the exhaust side

At the edge - the port is 33mm, but because of the taper the port is graduated all the way back to the bowl

You can | Sad

.... OR you can ask for help!!!
