Default hardened valve seats L78
Here's one for the engine experts, I am rebuilding my 70 L78 to stock specs, have the original heads. I plan on running the stock 11:1 C/R and plan on driving the car as much as possible (spritedly I might add) plan to run 96 octane with booster, should I have the hardened seats installed (hate to cut the orig. seats) or can I get away with the original (freshened up, new valves etc.) seats. ??
I have heard conflicting views on this, what do the majority of you LS6, L72 guys run out there.??? Thanks in advance
