iq52. your completley wrong. no way no how is using .400 offset rockers on a factory head going to work without major modification. he should either buy heads that use the offset rockers, or like said above trade or sell them to get stock style rockers. if you think shimming them is the end all be all fix for the heads and rockers i would love to see the nunk you slap together for your car

And you know this because YOU'VE tried it? RIGHT?

You shim them on the rocker shafts to hold the roller tip over the center of the valve tip, like this:http://s1081.photobucket.com/albums/j351/heyoldguy/?action=view&current=greg496watson427094.jpg

and the whole thing looks like this:http://s1081.photobucket.com/albums/j351/heyoldguy/?action=view&current=greg496watson427095.jpg

The above "nuck" was a 496 with RPM heads and a single 4bbl that made 642hp @ 5800rpm and 642tq at 4600rpm, 600tq from 3500-5500rpm on 91 octane.

This next "nuck" was a 451 with RPM heads and a single 4bbl on 91 octane.

Yeah, that's right 786.9hp @7200rpm

How's about this small block "nuck". A set of Indy RHS LA 360X heads that we set up to use Chevy stud mounted rockers for .750" lift and 8000rpm:
