Valve Job?
The engine is a 400M in a 1979 F-250. After disassembling it yesterday it appeared everthing was factory Ford install. The engine has 127,000 miles on it.
If I have the heads remachined will that cause lower engine problems later? I am doing this in-frame and trying not to do a complete rebuild just yet.
Maybe post in the 335 engine series forum.
The topic isn't 73-79 specific
and yes in some cases re-building the top or bottom just by themself will cause the NON-rebuilt system to fail.

"sounds like mickey mouse plans to me, don't do it that way :/"
Think back, at least one did, right? ;)
Listen to -him-. ;)
Here's an idea, good or bad... get a running 351 and slap it in there temporary, then resell the 351 when you get your 400M done like you want?
Or something like that? :)
Or nothing like that? :)
Alvin not good or bad, just butt-ugly in AZ
