340 X heads advice

barracudadave67 said

Im going to look at a pair of "bare" 340 X heads on Tuesday 4/9/19. What should I look for as far as problems, I not a engine guy, so I could use some advice.
I have a early 360 short block that I want to put together for my 66 B-Cuda. I bought it minus the heads. Guy kept them.
I can get a set of 3769973 heads cheap, don't know what size valves are in the 973s. I know this block had J, or X heads on it, before I bought, so I think the X heads would be the way to go.
I also have the A-904 that was hitched to the 360 block. I will turn an already installed 8 1/4 rear.
Thanks in advance
Dave

You didn't say what price you could get them for, I wouldn't pay over $200.00 for bare castings ...........that said buy them and resell them to some one who desperately needs/wants them. Then take the money and buy a better set of heads. There are 3 kinds of people who want "X" heads, restorers, class racers, people who think "X's" are the be all, end all of small block heads. Any small block head with a 1.88 intake valve will become an "X" head equivalent with the addition of 2.02 intake valves. You have stated the "X" heads are bare, so you have to buy valves anyhow, just buy a set of 2.02's and have them installed, springs to match cam, knurl guides if they are loose.
