I'm assembling my ls6 motor and I got these stock 243 heads used off of corvette forum, I didnt notice it until now but it looks like the coolant passwges are blocked off? One is on the front of the passenger head and the other is on the rear of the ds head? Does anyone know if this is even possible on my coolant tubes and plugs the barb is hollow but these look to have a screw or something in them.
