If it were me, I'd want to use the forged crank and 915 heads.
No matter which block he starts with , the later blocks would be my choice , if you are set on using stock iron heads then I use the 915 heads.

The 915 heads look original so they wouldn't have the hardened seats in them right ? the 906's look like they have had some work done to them recently how can I tell if they have hardened seats in them ? 10 years ago I would have just taken the motor that's on the stand now painted it and ran the crap out of it but I just can't do it now.. Did I grow up ?
The added cost of putting seats in the 915's is minimal in the big picture of the rebuild. The 906 is an open chamber head , not the perfect choice especially since you have the 915's .
Are you going to be putting 20k miles a year on the car ?

I'd use the best parts from all 3. Ideally you'd want to use the 67 block and heads. If you are going to buy all new guts I'd use the block/heads that require the least amount of machine work. Hard to say w/o seeing all of it.
If you think he should use the best of all 3 what leads you to believe the 67 block is BETTER than the others ?

meaning if the bore on the 67 didn't require bore and new pistons I'd use that.

what goofy MH heads do you refer too? #452 with the small peanut 5/8 spark plug? thats whats on mine and works fine fora stock street engine,it has better cooling pasages with harden seats. IIRC are you talking baout the heads like on a 413 with the WP housing bolted to the end of the heads?

More patient, for sure. Back in the day, a guy didn't have money or time to build the perfect scenario. Its this type of issue that stalls a project out for too long. Slap the 'MoHome' mill in while you take the time to build a good one.

Use the forged crank, 915 heads and whichever block checks out the best......no real world advantage or disadvantage to any particular block choice. If they were all mine, I'd plan on using the 67 block just so I wouldn't need to totally disassemble the other two motors, If it checks out, great....if not, check the next 440 block in line. Dave

You should be able to see where the seat area has been machined and a hardened seat has been pressed in. I'd imagine it might be difficult to see on a used head with some carbon build up. If hardened seats were installed, it will probably only be on the exhaust valves.

another vote for using the best stuff from the 2 or 3 engines.
Me too! the advantage of the two newer blocks they have the stiffening rib up the side of the blocks that help with an early block tendency to crack between the frost plugs. steel crank, new pistons, 906 or the 516 heads or better sell both and get aluminum!!!!!!!!!!!!
