New 408 build finally started

With regards to Indy house brand rockers(the Dove rockers), I’m pretty sure the 360-1 rockers and 440-1 rockers are the same.
The spacers and hold downs are probably different, the shafts are different, but I believe the rockers are the same.
As such...... they should be too long to work on a stock style SB head.

One possible issue I see that could arise from using W2 intake rockers would be if that moves the pushrod over “too far”, and you end up with some interference with the pushrod and the intake bolt.
