Another 302 Head Question

MoparLeo, the motor sat for 15 years with fluids in it before I even found the truck. It was my great grandfather's. My parents sent the motor to an engine builder. At the time, I knew very little about any of it, so I am unsure as to what was done. The engine did sit for about 3 years after assembly, before being started for the first time. It sat without fluids, on the floor, in the garage linked to my house. It has ran perfect all summer, besides for these leaks.... and I understand about the thin vs. thick gaskets. Sure I'm in college for Marine Engineering now and some of those big 2-stroke diesels don't even utilize head gaskets. My primary reason for that is the possibility that the block itself may not be true. Thanks for your insight!
BigBlockMopar, I have learned very much over the past few years. I agree with what you're saying, and I understand the concepts of fuel suspension and "rough" surfaces. As for being cocky, I am ambitious but I don't get away from myself lol. I wouldn't go near as far in depth into a "home porting" job than described by 1wild or the other thread that had videos. But being my first time, I was looking for insight on whether or not there were any DANGER areas compared to the older castings. 302s seem to be a head that like to warp or crack; is this because they are thinner? lower quality metal? or a side effect to the lean burn and emissions, running too hot? Thanks
