Dennis- click the like in my signature and have a look at my 230. The head is from Earl Edgerton of Edgy Cams, Edmunds dual water heated intake, 3/4 cam, holley webber 5200 carbs, Kansas Kustoms split exhaust manifold.
Don Coatney over on the P15-D24 forum has done the tranny swap, he'd share the info for you.
