First build

John Ayers said
I bought a 1965 Barracuda Formula S. I found out that both heads have cracks. I was told that these can be pinned. The cracks are near the water jacket and not around the compression area.
Has anyone repaired these heads and had success, I'm concerned?
I was told that 318 ci and 340 ci heads will fit on the 273 ci block, is this a fact?
I was really hoping that I could keep this vehicle stock but have a limited budget. Any suggestions?

Problem solved below. Good man below.
Just for your information;

The first 2 years of the small block have smaller bolts installed at a different angle. IF you use a newer head, you’ll need a newer intake or grind the old intake bolt boss to work.

The small bore of the 273 limits valve size so a stock 318 valve will fit inside. A 360 or 340 intake valve, 1.88 - 2.02 respectively) will not fit.

I have many sets of 273 heads for you, and may have the perfect set! They're 65 heads, have been stripped and cleaned and can come with all of the valves and springs and other items that were removed! Best of all, they'll be cheap, because shipping will be a big factor here! I live in Michigan, near Ann Arbor if you live close by! Message me and we can talk about getting you what you need!
