Panic, I have a louis tool to lengthen the pushrod holes if required. The studs are pretty much parallel to the valves, so no help for roller tip placement.
Someone a while back had asked what the valve angle was on a 6. Well according to my $10 angle finder, I got 9 degrees-ish. Interestingly, the top angles away from the pushrod, not towards it, opposite of a SBC. This means the air has to turn past 90 to go through the valve. Think how much difference going from 23 to 18 makes on a SBC. No wonder the hybrid heads add so much power. I truly didn't realize how poor the six head design was until today. It's really a good argument for drug testing in the workplace IMHO.......
Tom, I feel the same way about the pushrods, but I've changed so many things from stock that stuff like this is inevitable. The cam base circle is different, deck heights have been changed, The head has been milled somewhat, I don't believe the valves are stock length anymore either. I would have ordered two extra pushrods anyhow, now they'll just be labeled "I" and "E" is all.
