Need Aussie valve train recipe

Hi gang, I ordered a set of aussie 2v heads from Ausford. I plan to have them machined down the street,they will be going on top of a 351C 2v remanufactured 10k ago. I ordered from PAW a comp 270H magnum cam,comp
hyd anti pump up lifters, comp single valve springs and retainers. I think I am alright so far. depending on the feedback i get i was planning to order the following parts to finish this offaw Molly push rods, polly seals, multi groove keepers, paw stainless valves, Ford racing roller rocker arms. If anyone w/ experience with these heads can give me insight on my recipe or their own proven formula please let me know before i sink a grand into these heads. a couple things i am curious about are valve size's, ohio vs australia and pushrod guides, the Ford arms are bolt on with no guides needed. some extra info on the block,4v 600cfm performer carb,2v performer manifold,hooker comp headers,FMX/stock converter,9in. 2.75 open rear end,soon to be 3.00 traction loc. thank you's in advance for any help you can give me. Scott

actually i dont know where the hell my heads are, ordered them on the 10th. and ausfordparts web mail dont work. when they do arrive i will just go with what i know..... what i am most concerned with is valve stem height after the valve job.
