Question for the builders, how do you figure out if a cam can be swapped without re-configuring the heads? I'm running a set of woods 400g cams now and I have a set of 9bg cams on the shelf. Would these be considered a drop-in for my current setup, or would the heads have to come off and go back to the shop for adjustment? CR 10.5:1, using woods w188 valve spring

 

Wood 9B, has more lift, requires more compression for starters.
It "might" fit, but more to equation, if looking to fully optimize the package.
