Im figuring the MOST likely culprit is the head gaskets...The car sat a long time & Im sure w 12:1s the cyl psi was too much...
If the block/head is cracked Im only out $50 for gaskets + time which is what dye would have cost AND I dont have an air compressor/leakdown guage either although Im gonna do a compression test prior to removal.

thanks again,
Bob
