Let me know what you think i should change on these before i start porting, goin for a bigger streetport on secondaries and pretty mild on the primaries. I got a RB template but I dont dig it.

And what do you all think about using these side housings- i have solid corner seals and atkins side seals.

jdmrbust 12-10-2005 09:11 PM

well- no one has any advice tonight?

RB has a good reputation.



What is it about their port design that you don't "Dig"?

Whats the diff. between the solid corner seals and the atkins ones?

WTF? It looks like your side seal was chattering, But its not in line where the sideseal would pass.. What is that?



It looks like you have rust coming through the chrome, or is it the pics that makes it look like that..

What chrome? Its a cast iron side housing. Nitrided, but not chromed.

I was thinking the same thing. RB has some very nice port shapes.
