Question for the group....

I have a mild 350/350 in my street rod.
'77/'79 350 4 bolt, 1.94 62cc heads.
Running a 3.55 rear.
750cfm AFB.
Block hugger headers with dual full length exhausts.
I like the off idle to 6 grand driveability..
Runs fairly strong, but nothing spectacular.
Has a nice idle, nothing lumpy or anything.
Good vacuum at idle.
Don't know the cam specs.
Would a change to 1:6 rockers bring anything to this combo?
A 'lot' has to come off for a cam change.
Anyone have experience doing this?
Just curious.
Thanks ahead of time.
Jeff
