Today, dollar for dollar, is the 318 faster than the 340 ???

Just to kinda slide/make a point the mopar crate engines used new production line engines. Then when they quit producing the factory engines they started using remans. And made pretty good reliable 380hp engines.
And not just mopar done that

The only thing I would be worried about is the head work on the guides.

The thing alot of people are leaving out is that forged pistons are hard on cylinder bores and have alot shorter life span. $3000 can be done reliably and make pretty good hp. Factory has been doing it for years

That’s not true. A forged piston isn’t harder on cylinder walls. Their life span is far better than a cast equivalent. Plus you get the benefit of a far, far better ring pack. That in and of itself makes more power, seals better and will live far longer than the thick rings that come on cheap cast and KB pistons. Again, it becomes penny wise, pound foolish. And if we say let’s do your 3k reman, you are stuck with the cam they pick, unless they have options. And on top of that, you didn’t get the China knock off heads that 318WR said he could do for his 3k build.
