well i narrowed my choice down to 2 different heads -- AS LS6 or TEA LS6. i definitely want to go LS6 since they will work well with a stroker kit that i eventually want to get. my question is with either of these heads what other parts will i have to buy? head gaskets, but what kind? what about head bolts? also, i already have REV dual valve springs with titanium retainers, so will they be compatible with either of these heads? please give me so knowledge . thanks
