GN1 Porting?

[GangsterMD]

I was putting the gaskets up against my new heads and I see there would be some room to gain in the corners. Is there anything to worry about or to gain by touching up the corners? Also the water jackets are out a bit - is that a big deal?
Thanks

what does the gasket look like on the intake manifold? is it port gasket matched?

Intake Head Porting

Yes, I actually started another thread on that... I have ported the intake to match the gasket already.

my new GN1's are the same way. I'm also pondering whether or not to touch them up a bit.

My first impression is that it's probably not a big deal as it looks like these heads make up most of the flow area in the bowl area when compared to stock heads.

Do not lower the floor of the port unless there is a big mismatch.
It's always better to raise the roof of the ports.

Just open up the gasket

Doesn't Champion recommend the 1200 gasket for the GN1's?
