These questions are tough.
I'm not sure on the pushrods.but I would bet that the stockers would work.
Now the cam, don't know the specs on it. But there is only one way to tell if you can up the rockers to 1.7s.you will have to check piston to valve clearance.what I would do is wait on buying them.then when you go to put the heads on.bolt up a set of the stock arms and do your check.that will tell you if you have enough room to up.if you do have room then I would suggest going 1.7 or 1.72
Lobe lift x 1.7 = total lift.
Lobe lift x 1.6(stock) = total lift

Also if you can't figure out the pushrods you can get a adjustable pushrod from summit or jegs really cheap.then you set it to the right length then measure it.this is the correct way to be exact.but someone may know.[COLOR="Silver"]
