Just got my gasket kit so I can reassemble my 312. The head gaskets are 7999PT Fel Pro and they came with an instruction sheet that calls for drilling holes in the block deck and matching head surface. These holes would be located between cylinders 2 & 3 and cylinders 6 & 7. an upper hole of 11/64" and a lower hole of 1/4". The holes are in the gaskets and according to Fel Pro drilling matching holes in the head and deck will aid in cooling the motor. Is this a good thing ? Or should I avoid the proceedure ?
