Default Re: Head gaskets 351

I had a 351 head gasket that I compared to a 401 and it definitely had a smaller bore opening though it is said you can use 401 head gaskets on the 351. Not to change the subject but I have done several cylinder head conversion on the Jeep 4.2(258 ci) inline six to the 4.0 cylinder head and the proper head gasket to use is the 4.0 which unlike the long stroke 4.2 has a considerably larger bore. So evidently it's ok to use a head gasket meant for a bigger bore engine within certain parameters.
