well your exhaust valves get very hot during its running cycle, when exposed to much colder air it contracts the metals in that valve in a pulse matter. thus causing chipping valves...its like throwing very hot class in cold water....then again some engines have alot of heart which makes them last longer then others...u should get headers, no headers dont gain you noting but a melted fender....
...sorry, but i have to backup jsaulgody, he is right
glad to hear that the engine is still running good, very very good news :) you probably didnt do enough to damage the valves and other components, let alone engine bay components subject to those blue flames
@celtic5yamum I took the engine apart a week ago because I spun a bearing @ Mosport, and I had to put the head on a spare block, so I did an inspection of everythng while I was at it - No cracked/burned valves at all. Everything seats properly.
Maybe your theory is correct, but here, in this case, it does not hold ;)
@Jed118 Their theory is one proven on paper but not one perfectly proven in reality. I have seen my fair share of engines run with no headers during the build/ rebuild and have no problems (even when run so that the valves would be hot). Theory is that the cold air would be sucked back into the engine when shut off and the cold air touching the super hot valves would crack them. Though stock exhaust flows less than 1 psi normally, and can still pull air back into it.
its a burninator

Exactly how? It's been a year... compression is stil 165 across the range man, and the timing chain did not skip a tooth.
What's your rationale behind this?
