Can anyone help me identify the correct gaskets for replacement? Part numbers? I'm having trouble identifying my engine on the NAPA online site. Thanks

The 261 gasket will have a larger cylinder bore size (3 3/4" instead of 3 9/16") and vent holes in the gasket between cylinders for the "steam holes" in the block and head. Other stuff like intake/exhaust, valve cover, fuel pump, etc. should interchange with a 235.

Jerry Besides the 235/261 head gaskets being different: To be safe, go with a 1956 and later 235/261 gasket/set. The 1954/55 sets might come with the earlier water pump gaskets (although, I have bought 235/261 gasket sets that included both styles of water pump gaskets). Also, 54/55st truck oil pan gaskets are different from 55-2nd and later oil pan gaskets (but, again, I have bought 235/261 gasket sets that included both styles of of pan gaskets). | | | | | Joined: Oct 2006 Posts: 1,847 'Bolter | | 'Bolter Joined: Oct 2006 Posts: 1,847 | use the remflex gaskets for the intake/exhaust, they are about $35, and worth every penny. I haven't actually used them on the truck, but I have used it on many other applications, the absolute best, bar none. | | | | | Joined: Jan 2000 Posts: 2,074 'Bolter | | 'Bolter Joined: Jan 2000 Posts: 2,074 | I just installed Remflex intake/exhaust on my '54 235 in flatbed, so far they are great. Just shop around for good price, mine came from Summit. | | | | | Joined: Jun 2011 Posts: 5,096 Crusing in the Passing Lane | | Crusing in the Passing Lane Joined: Jun 2011 Posts: 5,096 | Remflex gasket bulk material only comes in large pieces for my 503, so I had to make own set, hope it seals well, will comment after I get it going.
