I bought these thinking I was going to build a bad ass small block, but decided against it.
I paid $900 for them a couple years ago, and I'm hoping to get about the same for them.
The previous had this to say about them:
THESE ARE SMALL BLOCK CHYSLER HEADS THAT ARE FULLY PROFESSIONALLY
PORTED AND POLISHED.THESE ARE THE FAMOUS HIGH PERFORMANCE 340 X
HEADS. THESE WOULD BE GREAT FOR THAT RACE CAR OR HOT STREET CAR
OR STOKER ENGINE. THE NUMBERS ON THESE READ 2531894-E AAWJ 340 X.
THESE ARE SET UP FOR THE ADJUSTABLE VALVETRAIN. THESE HAVE THE 2.07
INTAKE VALVES. THESE HEADS HAVE HAD EXTENSIVE MACHINE WORK DONE ON
THEM TO MAKE THIS SIZE VALVE FIT.THESE HAVE THE CROWER SPRINGS AND
1/2 SOLID BRONZE GUIDES.THE PICTURES REALLY DO NOT
SHOW THE
EXCELLENT PORT WORK THAT HAS BEEN PERFORMED ON THESE HEADS.
THE OWNER OF THESE HEADS CLAIMS HE HAS OVER 2000 DOLLARS INTO
THESE HEADS FOR PORTING,PARTS, AND SHOP LABOR.THESE HEADS ARE
COMPLETE AND READY TO BOLT ON. THESE WERE ONLY ACTUALLY FIRED
UP ONCE.
I have seen nothing wrong with them, they are about as maxed out as factory cast iron heads can be.
Here's the pictures:
