340 Aluminum Head, Rocker Arm Upgrade

-
I cant argue cause I don’t really understand it all but it’s in the geometry of the pushrods of the 1:6 that benefit more so than the 1:5 rockers. I’ll have to go read Mikes articles 4 more times. Maybe my thick skull will understand it better then. Lol
There's no denying it opens the valves a little sooner, but you're not talking about a magical 50HP difference. Who's to say on some combos you might lose power? IMO it's a lot more important to get the geometry on what you HAVE correct first.

That’s just it. 1:6 HELPS the PUSHROD geometry. Especially if you go with a socket adjuster instead of the ball. The longer the push rod the better. Not to be confusing this with correcting the geometry of the rocker pivots. It also help longevity. But you are correct. I doubt if you would even feel the difference on the street.
 
The main purpose for me to go with 1.6 ratio rockers is because I am preventing this project from spiraling away from me. What starts as replacing the intake goes to replacing the heads, rockers, then cam, timing set, bearings etc. Before you know it, you're rebuilding the whole thing, which I don't want to do. So I'm forcing myself to leave the shortblock alone at present.
