Mopar Stage VI 6 heads questions
My suggestion is, the first thing you should do is check the valve drop for all 16 valves before going any farther.
It’s not uncommon for them to vary .030……or more.
If they’re within .060, then getting them within about .015 or so for all the intakes, and the .015 between all the exhaust would be the goal.
I’ve also seen where on each head the drop is close between the intakes, and between the exhaust, but the two heads aren’t very close to each other.
If that’s the case, then you have to determine what needs to be addressed to get them closer to each other(milling, sinking valves, or some of both).
Get a game plan for how you’re going to address this……if it’s a problem on your two heads.
One other thing you’ll want to check……..
Put a dowel pin on each end and rest a straight edge against them. Then measure from the straight edge to the intake surface at the two ends.
You’d like them to be within .010”.
I will say this, back when these were popular, I worked on quite a few……….and every set had their own little surprise.
As for lift, make life easy for yourself and plan on running less than .700”.
