Ported X head pics

Thanks for the reply. I appreciate everyone's input. The floors I havent touched since I stalled a couple years ago. Altho I have done some cleanup on #2&4 floors. 6 and 8 floors haven't been touched.
On the ssr I smoothed very little with a stone. Mostly hand sanded 80 grit to smooth it out.
Worked a little more on chamber side today trying to get in between straight wall and outer guide tail. A 4 or 6" mandrel for my spiral rolls would be nice! :BangHead: I cant get in far enough with drums and the 6" burrs I have are too wide. I was able to get in with a short barrel style.
When you talk working the SSR are you talking from port side or bowl side?
Heres pics where I'm at 2 and 4 floors were touched up couple years ago.
Also any theories you can share in a pm??

Wow! I can't believe no one want to comment on this.

Using your statement on the first post this is my thoughts.

The guide and roof get blown out to get max port potential......." that's not you".
There is a reason chry put that blocked off hump there. i have my theory but won't share them or argue others theory.

YOU need to open up the smallest CSA(cross sectional area) and that is NOT the PRP(push rod pinch) and it Is NOT the roof or guide boss.

It IS on the floor at the beginning of the SSR (short side radius ) aka you need to make it just a little bit wider.(wall to floor work). Don't get crazy here, just improve the width,
And it IS in the bowl, (Make it 88% of the seat) and the Most Important Part of it all is the 3 angle valve job!!!!!

The bottom cut of the 3 angle cut(65 or 70*) Will cut out a LOT of material in the blow. My suggestion to you is blend in that bottom cut and call it a day!!! even if it is less then 88% in the blow area.
Remember you can always, cut more metal out later, but it is Hard to put then metal shavings back in!!!!!

One final note: I'm not telling you all of this because I'm some PURIST X head person. i would give you the same EXACT advice if you were looking to improve a newer smog 360 head with a 1.88 valve.
