Hi all, Thanks for the responses on the Hemi head numbers. I was told that the 1556157 heads were from a '55 C300 and the information so far does not dispute that, albeit they may also have been on a Dodge truck. Strange that the '55-58 parts manual does not identify the '55 300 heads. The number is in the center of the head under the rockers so the next time anyone changes their valve covers, check the number for a positive I.D. The site that Dave in New Zealand refers to is great for thes part numbers. Thanks Dave. Thanks again to all, John Cote Guilford, CT. -----Original Message----- From: Dave Agnew <fnnutz@xxxxxxxxxx> To: cotejohnr@xxxxxxx Sent: Sun, 13 Nov 2005 10:39:11 +1300 Subject: Re: [Chrysler300] HEMI Heads Hi John, Maybe I can shed some light here.
