360 oe iron block iron 308 heads felpro 8553PT gaskets. 4th try! what am I doing wrong. geyser starts in the coolant after several minutes. can I use a touch of sealant around these added holes?. visual on the fire ring appears OK. thank you for your time. RR EDIT the dark perimeter is where I had to slightly dremel to remove the fluff from the hole drilling & that is what I am wondering if I need to fill with something (the right stuff cement? or ? I gotta get it taken care of this time!
