actually talked to my dad and he said just that, have a gasket template made into a solid plate. luckily for me the plenum separates from the assembly so i can actually port the top a bit too.

 

If I may chime in, I did the f23 manifold swap on my f22b1 Accord. It's not as easy as it looks, and people claimed to see a 10hp increase with it and the Hondata intake manifold gasket.

The only difference I noticed was I could hear Vtec come in and hear more air in the manifold itself. It's weird but I feel there was an increase in performance. No dyno results though.

You do have to buy an adapter plate though for the IACV, which I paid 50 dollars for, and extend a few wires along with coolant lines. It takes time to do the swap.

I do have two f22b1 intake manifolds lying around that I am going to clean them up and sell, possibly port them if you're interested.

 

i was thinkint about the f23 but thought it was too expensive and complicated. i do already have an f22b2 intake manifold cleaned and ripped apart. i want to port this one but thanks for the offer. i need more or less now advice on how to port it. my dad told me if i do too much it might actually make things worse. any advice there and how much and where to port it? thanks

 

There's a company called Gude that makes intake manifolds for the f22b sohc vtec motor. You should check it out. You can also see a picture of it if you visit andysautosport. I was looking into that also and they seem to be the only company I found that makes an intake manifold for that engine.
