I actually approach it the other way. A dropped valve is horribly bad and destroys so many parts that I wouldn’t feel comfortable using stock valves/retainers on anything other that a stock rebuild. Pretty much sums up my approach as well. Aftermarket valves are cheap compared to the carnage they create when they break...

I've put new valves in everything I have had my hands on. On a core motor you often have no idea what kind of miles or abuse it has seen.
Also, as mentioned guides installed but not reamed to the correct size can hang up and cause a real mess.

Are you going to use the heads in a more radical application in the future. If so put the money in good parts now so you do not have to do it twice. Most of the problems in the old days was lack of oil and kicking a rod out the side of the block with a 340. It is all about oiling and clearances do research and pick a builder you can trust to do it correctly, head and bottom end.

Although many builders do things slightly different I dont think there are any real big errors in my ways, because my builds run good and dont come apart.
Back to the point of this build, everyone says plan for later and thats good thinking. But not every build needs a forged crank, pistons, and h beams.
Not every build needs to be a stroker.
Many seem to forget the old days when "worked" stock parts and a level head behind the wheel could go a long way.
I know this build here will come apart easily if I tried and it needs to stay under 6500.
So for me knowing all this its just a 318 that will run well, I wont be looking for street action in this build or this car, well maybe run a stock 340, or a 302 or 327 but still I know a modern V6 would hammer it.
But im having fun with this build and alot of the questions I ask are simply because im not well versed in some of the more simple oem parts and there uses and limits.
Ive a really nice set of J heads with 2.02 stainless valves or a nice set of edelbrocks sitting on the shelf, but ive chosen to use a new nos set of castings with hardened seats already installed, but with some port work and bigger intakes and see how it does.
But the basic things with this is no different then a big inch stroker, good machine work, good planning, being clean and clean again AND not being afraid to ask others questions.... and for me these things lead to good builds.
