Really nobody on here can answer those questions. Before you install them you will need to cc the chambers and use a compression calculator(try a search) to determine that. You want to think about both static and dynamic compressions.
As for the pushrods....as stated before you have to get a pushrod length tool. If you look through the stickys and do some searched there is a really good write up for it.
