"question: Will a a1 head work on a b1 block. Also, the b1 block is bare and I'll need to get a crank, rods, pistons, oil pan, ect. Is there any certian combos to make for a good LS bottom end with out spending a crap load of money?"
yes that head WILL work...
no good combos that i can think of that would be worth it... just get her back together and save for a GSR longblock...
