Fel Pro 1047 ??
I am build up my Dart block (Big M) with World heads, I picked up the head gaskets, FelPro 1047's and the instructions state to open up the 3 lower water passage holes 2-1/2" 1-5/8" on MK4's & HiPerf blocks, the "speed shop" where I bought them said not to open them up for marine use. What to do, open them up or not?
Thanks-
