Seems too light on pressure to me. At 250 lbs. on the seat, if you lose 20 after break in .....

I use a PAC 1356 on all new heads or freshens I do. On my personal engine I used a Manley 221420 but set them up taller because I have more lift.

Valve weight ? Lobe duration @ .020" minus lobe duration @ .050" = ? Rocker ratio ? Peak rpm @ the stripe ? |
