I'm running them with this cam, installed @ 105 intake centerline. I have 915's cut .030 with .214/.188's, pistons @ .023 in the hole w/steel shims. The depth was near .100 but the radial on the intakes was tight @ around .050. The notches did seem to be at 15 degrees and I needed to drop the compression and weight a little so I re cut them to 18 degrees with another .050 radial. The decks are almost a 1/2" thick so you can cut at will...
