rate now in the wanted section i have a post looking for a adjustable timming plat no cast junk, anyways have a few questions, if I advance my timming will it take away from my bottom end power? will this help me even though I trail ride, can you advance your timming with a stock head or do you have to run smaller domes? and in order to run a cool head with smaller domes do you have to advance your timming? I have a trail port and wesco pistons, stock head and was wondering whats the best advance +4? will this hurt my motor at all, and am I on the edge with +4 or is +4 just fine for my mods, I'm looking for more reliable power. thanks, Matt
