Dear Lord. Wasn't that like, 1978? Luckily, Mopar guys never throw anything away...somebody still has those little plastic cut-out templates laying around.

The only problem is....... They instruct you not to do what's required if you're really trying to see some nice gains.........which is rework the short turn.
I've lost count of the number of bowl blended, ported, big valve bowl blended, big valve ported 906/915 heads that I've had on the flow bench over the last 25 years that didnt break 240cfm......... All because the short turn was left untouched.
It's a double edged sword......... Don't rework the short turn......they don't flow much. Rework the short turn incorrectly....... They don't flow much.
This is why for the novice or first time porter, the 346/902/452 head is a much better choice. Ther basically is no short side radius to screw up. Just blend away the sharp edge, along with the rest of the normal bowl blending..... And you have a decent head.
I could probably rough bowl blend a 346 head in less time than it would take to cut out the templates.
Come to think of if, I had someone send me some stage v heads with big valves that were done using the stage v specific templates...... Mid-240's iirc.

They're on the shelf, next to the .654 mushroom tappet cam. You never know when you might need something like that, right (?) "Tonight, on this episode of 'Hoarders':"

Last one.....
A- "Ported" 906 head, SI brand 2.14 valve, no back cut, valve job done with a radius for bottom angle. Pinch opened to 1.070, guide boss trimmed a bit, some short turn work. Didn't look too bad, and actually didnt work that bad in the upper mid-lift compared to a lot of what I see of these things.
B- open bowl more, relieve chamber adjacent to valve, longer top angle on valve job, a little more work on the guide boss, lay back the short turn, back cut valve...... Same cylinder as above
Lift-------A/B .100---70.4/71.6 .200--124.4/156.6 .300--180.5/217.1 .400--229.4/255.1 .450--241.9/257.7 .500--243.8/258.9 .550--248.3/259.7 .600--248.3/258.9 .650--234.3/258.9 .700--234.3/259.7
The newer heads??? 902 head(1974): A- OE valve with back cut, grind 3 angle seat, less than 10 minute blend
B- open bowl a little more, bullet nose guide boss, pinch to 1.025", Manley valve with back cut
Lift--------A/B .100---67.2/ 70.4 .200--139.0/142.0 .300--202.5/205.4 .400--230.5/244.5 .450--237.0/249.4 .500--240.7/254.0 .550--243.8/257.0 .600--245.7/253.2

Who in the heck would mess with those lousy 906 heads. Oh that's right, we did and had to 28 years ago. LOL. Those good for nothing super stock springs too. I haven't figured out if it's stubborn or cheep, maybe I just wanted to prove the old junk can work.

Baaaaaahahahaha, I did until about a year ago! Found them in a drawer. Hey, back in the 80's, they helped me get my 440 smogger motor duster into the 11's.
