I really like the comment about "hearing" a problem, i.e.; rockers not set right, collapsed lifter, bad bearing, timing to far advanced/retarded, and the llst goes on and on

Especially new motors need at least 21 inches of exhaust on all ports to keep from damaging the engine. Just an ol' tuners 2-cents worth!

The old "burnt valve" scare is an old wives tale from the model T days. I don't buy it and never have. Neither do most builders. Drag racers don't have a problem with burnt valves and they run them as hard as possible and then just shut em off.
My comment about hearing a problem was referring to a rod, piston or wrist pin knocking, which you can hear just fine, not a lifter ticking.
I wasn't thinking about the OP having the body mounted though. I definately wouldn't do it with a fiberglass body that close to the exhaust ports.
