The assembling cost is then appx 10% of the engine value, in parts. So it is no big deal. More important is to have it properly done, and documented, and a warranty in some way against assembly errors if something bad happens at a later stage. An unskilled assembler can easily destroy your high value parts, or set them up so they self-destruct. I think that will be all the difference. Saving 2-300$ is no deal if the 10-15k$ engine fails....
If it is a bread and butter sbc, then it is a completely different story. But, you got a Hemi....Keep it living, too many Hemis went down the drain. The worst engines I work on are Hemis that have had multiple repairs/overhauls.
