Look at the adjusters on the rockers.......Those pushrods are way too long.
Brother, do some research, tear it down, check and measure, re assemble with new gaskets. This may sound like a lot of work, but trust me...it will be a fun learning experience if the engine looks good inside. (It will suck if it needs machining...but at least you'll know).
Ask tons of questions here......Lot's of great advice.
@krazykuda has a great engine re-build tutorial (with pictures) to help you through if you need it.
My .02 cents
