Its a 59 degree head/block with a solid roller. This is from Ryans website.
To make the situation better, you can use an offset intake lifter. The problem here is that most lifter companies do not cater well to the Mopar crowd when it comes to offset lifters. In fact to the best of my knowledge, no Hydraulic or Flat tappet lifters exist in .904" Chrysler diameter. A couple companies offer an offset Solid Roller lifter, and generally speaking, when you are thinking of running a W7/8/9 head, you are probably already thinking of running a roller anyhow. One of the problems I ran into was the fact that the Comp Cams #892 "Super Roller" lifters don't fit 59 degree blocks? No way, no how. The rivet design on them will not clear the lifter valley area, even with intense grinding. You will most likely hit the water jacket if you try to make these rivets clear. The lifter I am currently recommending that everyone use is a Crane .903" Chevy Solid Roller lifter with a .210" intake offset pushrod cup, and then have Crane install Chrysler "V" Link bars on them. In a factory block, these will allow a 3/8" pushrod to be used. If you want to use a Hydraulic or Flat tappet cam, then I am recommending just use the standard non offset AMC style lifters, and a 5/16" Heavy wall pushrod like a Smith Brothers .080" wall Chrome Moly unit.
