well there are a few things you need to decided. Mostly on which generation 13b. I would recommend use of S4 or S5 13B due to them being the most common, lowest weight and an overall lower cost. For the ease of a swap, if so inclined, you can use a 12a front cover and have the front cross brace if it makes the swap easier.

cheers . looking at s5 block with s4 rotors could you tell me a bit about different porting, bridge, tall port, pp etc

Welcome, Porting also is determined by the type of induction you want to use as well, some types of induction don't like port overlap so massive porting is not always the best way to go.
