intake/exhaust gaskets

[boatingbill]

The Kaiser Interchange List gives a Fel Pro part number of MS8886b for intake/exhaust gasket set for the 226 engine. However, Rockauto.com lists the MS8886b as a intake/exhaust set for oval exhaust ports, and MS8886b1 as a set for rectangular exhaust ports for the 226 engine. Can anyone clarify as
I need a set for my '51 Kaiser Deluxe?

Actually, both will work. The B1 set was used on the 226 thru the 60s when the engine was discontinued while the B set stopped with the 55 model year cars. At least, that's how my parts book shows things...

Thanks Joe. The B1 set costs almost twice what the "B" set costs.
