March 8, 2011First off the motor is a 306 with twisted wedge heads and a trick flow stage one top end kit stage one cam. I think I might have a blown head gasket. What`s the easiest way to tell? If I do when I pull the heads off what`s the easiest way to tell if I have a warped head? How much porting and polishing can I have done to the heads? Is there a bigger cam I can go with and if so how much bigger and what do I have to do? What would be the best intake for the motor? I also have some coolant on the top of the block behind the water pump what else beside the heads could cause this? Would an exhaust leak at the heads cause me to loose vacuum pressure? How can I find out what pistons are in the motor and what compression I`m running?
I know it`s alot to answer but any help is very much appreciated. Thank you, Chris
