1Fast C10,
You have had good luck with them........ Glad to see it indeed. My experience falls mostly with full-tilt racing engines. The cost-is-no-object type. IE: Nascar and Porsche V8s I build my engines (myself) to turn 6000rpm ALL DAY. That said. I have had two sets of Chevy's lightweight castings (one Vortec=one "smog" crap) fail due to cracks between the valves. The heads could not take it. The "heavy" ones can. I know everyone out there cannot afford the ARAO Engineering 32 v heads or the like and some of you (?) want to get the most miles you can out of a engine before you open the old wallet. Hence the post. |
