Hughes rockers

I’m sure there is a slight edge in power/durability getting the geometry absolutely perfect. But I’m not going for prostock performance, the 383 in my Dart has been in 2 cars and tortured since 2011 with the same heads a ductile rockers... the sweep pattern on those guys about covers the entire valve head and it’s a mopar 557 solid cam. I spin it to 6800 every time I drive it and it shows no signs of any problems.
Maybe you'll get lucky, maybe you won't. Maybe the next guy will or won't either. It's a decision each individual has to be comfortable with.

I'm currently relocating studs on a Chevy, because the geometry isn't right on those either. Yet a lot of guys bolt the heads on with a lousy centered pattern that is way wider than it should be. I don't let that go out the door.
This is with .500" lift. It isn't perfectly centered, but I moved the stud as far as physically possible with the available inserts. It needed .100", I got .080". Btw, this is for my brother-in-law, so I'm not making any money from it, and I still wouldn't let it go out the door with poor geometry.20180606_142403.jpg 20180606_153959.jpg
