TOO MUCH VALVE SPRING

Only a few people have shown the math to get the loads, and those loads make it obvious that it's a non-issue. I vote run 'em. I'd rather have a little too much than a little too little, IMHO. The modest difference won't affect a darn thing on a hot rod.

If you plan to make frequent coast-to-coast trips, or put it in a truck and never rev it over 4k, the calculus on the decision might be different.
