I have kind of run out of money as i am loosing my job but don't want to keep the car off the road when i put it back together...

not worth the risk.. the main influences on the map from your list will be the cams and the pistons.. the pistons will effect compression.. to high compression and it will detonate and cause damage.. the cams will through the fuelling and ignition out and need mapping in.
it should be okay for running in.. and it could be checked both for running in and after to check safe though.
Head gasket thickness can be used to tailor the compression of the engine also.
