People can give you a close guess, but the best way (if you have the time for it to be down) is to asseble everything and then use a pushrod length checker to be 100% sure. They are under $20 and worth it imo.

You need to use a pushrod length checking tool to get the correct length you need. Without it all you are doing is guessing.
