Ok, i have a few questions reguarding a LS/B20 build, and i know you guys can help me.

1. will the p30 pistons drop right in the b20 block, like they will with the LS block, or will they require some kind of work? also, will LS rods drop into a b20 block without any work?

2. will a LS head fit onto a b20 block without any problems?

3. will the header and CAI i have for my LS motor fit onto the b20 block, or will i have to get some kind of custom work done?

4. will the valvetrain parts i have in my LS head drop into the b20 head, or would i have to buy different parts? or will my LS head just fit onto the b20 block?

thanks ahead of time for the help. its my first build and im looking to get this information before i start trying to throw things together.
