In the process of getting a set of Dart 355 CNC bare.Looking to go with Manley 11536 Int 2.300+.200 3/8 and Ferrea F2120P 1.890 sup alloy 3/8 and Isky 9905 [email protected] psi Hyrlr atleast thats what teague custom marine recommended. I have read several threads and alot of people are using 11/32 can anybody chime in and guide me in the right path. Also looking for the best deals on valves.

The heads come set up with 11/32 valves. They take .250 long intake and stock length exhaust. I use Manleys. 11854 intake (2.300") and 11745 exhaust (1.900) or 11743 exhaust (1.880")

About all you will safely get away with using those lifters is about 175# on the seat and about 450# over the nose. Personally, I would not use that lifter and go with Morels. They work.
