Is this cylinder head exhaust port crack an issue?
Help head experts.
Long story short. Heads were rebuilt by magnum machine & friend ran them on a healthy 318 for a year. Picked up in trade and have been stored wrapped in plastic indoors for 2 yrs? Brought these heads to Carlisle for sale and after unwrapping plastic in my hotel room found this crack on exhaust port I didn't notice before. Arg.:wtf:
Is straight almost like it is forged. Are these toast? They came off a strong running engine with maybe 1500 miles and 15 1/4 mile passes on em.
Thanks.
