For this project, waiting 4-6 weeks for the heads is no problem if it saves me 200 or more. Buying the heads in a few months, most likely. Putting the 440 together this year, maybe but doubtful. Installing it in the truck in 2022, nope. I have too many projects in front of it, plus, more to come with the bombcycle. We just got that in at the end of last year, and really barely made a couple passes.
