Tools used:
Carbide Burrs: amzn.to/3oHexDO
I'm doing a 01 5.9 Magnum , your videos have been alot of help.
A before and after on the dyno would be interesting.
These heads are capable of WAY more power than stock, and it involves smoothing, back cutting the valves, and deshrouding them...... the pinch point isnt the trouble....... dont forget to widen the shoulders on the short sides in and out, but be careful of water jackets
Biggest challenge on these heads is the pinch point - if you have enough material to open that about 0.040" you would like it.. Pretty good cleanup with basic tools here - but no, it didn't get ported.
Leave all that alone and just blend the bowls next time.
I use a sharpie marker even with a new intake gasket - red , blue or green .clean surface and mark it with a marker
You should use machinist indigo dye on your heads and a scribe!
I used a sharpie instead of paint. Seamed to work okay.
Can I use a wire wheel on the valve seats and it will be safe still?
Did you have the heads checked for cracks seems common on there heads
Gasket matching is a waste of time unless the shrouding in the bowls is addressed in these heads. The pinch is alot less restrictive than your claim and you've made it worse by gasket matching the pushrod pinch side.
