350 sbc(slightly domed) with 041 heads with 194 valves. Bent 7 of 8 plugs (champion)during start up the other day. Have run this combo before without problems. Now I have autolite 145 stock plugs in it but they are not burning all of the fuel (little wet,gas)
What plug should I run? Is there a short plug with a good heat range?
200 lap enduro races.
Thanks,

Champion J6C should work without any problems.That's all I've ever used on gas.

I did some research on the archives and found 2 posssible plugs to use.
43#TSR Autolite, then go to 44tsr if the plugs are still a little wet.
The other option might be autolite racing plugs 133 or 134.
Is there any advantage of going to a racing plug with a 9.5-1 motor with pump gas?
Any comments?
Thanks,

I run ac plugs in mine,especially if you run a little rich,43 is a little cold so i'd go with a R44 if it's gasketed plugs,R44t for tapered seat type plugs.

The 041 heads I had took the large type gasket-seat plug. The Autolite 353 plug works well for a standard reach plug.
