After a few years in the States i'm returning home and have an EB XR8 waiting for me. I admit to knowing bugger all about rebuilding and modifying engines, but want to learn with this car!

I want to take advantage of the good exchange rates and cheap parts in the USA before I head home and have selected the parts below to start my project - my questions are:

- Is there anything else you would get in the states to take advantage of the cheaper prices?
- Do the parts below seem like a good set up (from what I have read in this forum they seem pretty good)?
- Will these parts bolt straight on and physically fit an EB XR8 without any modification?
- I'm trying to work out the compression ratio using this site http://www.csgnetwork.com/compcalc.html but don't know what the stock 302 piston dome volume is - anyone know?
- Should I get / do I need hardened push rods for these heads?
