I know how you feel, I paid $9000 for a crate engine (different vehicle) which came with a water pump and oil pan and valve covers, that's it from Ford Racing, with all of the accessories I bought, all new , it was more than double that and I installed it myself. I didn't even use the water pump that came with it and I sure wasn't going to use any of the older parts from my last engine, even though some parts only had a 1000 miles on them. It just doesn't make sense to use any old parts once you are building a project, let alone opening up an engine. Trust me, this is a project. If you want reliability, do it right. I've done it the cheaper route before and I have had bad luck thinking like that. Most members that add a whipple s/c will even change out the alternator because it's a pain in the ars to change later, stuff like that should be considered as well. You don't want to take this apart afterwards. Good luck and I know you will do it right, since you came here looking for advice. Our advice is expensive, ha ha. Because we are Raptor enthusiast and don't want to see a good member being lead down the wrong path.I’m starting to come around to the idea, no matter how painful it sounds right now.
