best 360 spark plugs

[deathcharger71]

its time for some new spark plugs, just wondering what you all suggest for what ive got. 360 10-1 compression, .490 lift, dual plane, 650 carb, 271 gears for now, 2200 stall. i think im running champion now. im changing the plugs because the car sat for a while and i ran it with bad gas. i have had some problems with detonation in hotter weather, was curious if running a hotter or cooler plug would help with that at all?

I run Champion #2405's.  They're the platinum version of RC12YC4's

ok so it says for a 360 to use RN14YC, but for a 240 to use RN12YC. and at mancini racing it says RN12YC is for 9.5-10 to 1 compression. so am i correct that those plugs are meant for the 340's because they were higher compression and the 360's were lower compression so they used different plugs. and since my 360 now has 10 to 1 compression that i should go with the RN12YC plugs? and is the 2 colder then the 4 or the other way around??
