Matched pair of 3919840 Heads. These were used on 68-69 L78 396/375HP, L72 427/425HP, and L71 427/435HP engines. These are dated A108 and A118 which decodes as January 10th and 11th, 1968.
These heads were just taken to the local machine shop where they were cleaned and magnafluxed to check for cracks. Both heads were found to be crack free. There is also no porting or corrosion issues. The heads have not been decked/surfaced a lot as shown by the picture with the dimes on the deck indicators. This is a nice pair of unmolested heads.
