You want to learn about the early Hemis, 331, 354 and 392's.  Well here's a link to the Hemi Tech archive over on the HAMB.  You'll not find a bigger resource for early hemi info.

As for the intake, the 1951-53 331 and 1954 354 hemi had a wet intake.  So there were water passages that crossed over from side to side through the intake.  Maybe you have a leak near the back cylinder head/intake seal?

Looks like a Hilborn mechanical injection system on a 392.

can i put hardened valve seats in the 331 to avoid adding a lead addative? if so, where can i buy these? and should i get new valves with them?

  1954 354 hemi had a wet intake. 
 
I thought the 354 didn't arrive until '56?
 
I was just reading an article from a '59 Hot Rod magazine where a guy was talking about stroking a 331 to make it a 354.  I found that historically interesting.  Why stroke the former when you could just get the latter?  Kind of like doing a lot of work on a 318 when you can just get a 360.
 
(My Uncle from NC sent me a bunch of old car magazines - the histirical perspective is fun to read!)

Your right...my mistake.  The 354 was a late 55 and 56/57/58 motor.  The early 354's had a wet intake like the 331's, then they switched to the dry intake like the later 354/392.

As for stroking the 331 to make it a 354...well there was really no stroking involved.  Just a .125 over bore to bring the displacement to 354.  These old Hemi's are known for there generous cylinder wall thickness and many guys have bored them .125 or larger with no problems.
