high compression head

[Mike]

Good afternoon,

My head gasket is seeping between # 2 and 3 cylinders, my question if I am going to replace the head gasket I would like to upgrade to a high comp. head. My engine has babitted bearings with 6,000 miles on it, should I go with a 5.5 or 6.0 compression head? Is the 6.0 head look just like the original? I am leaning toward the 5.5

Thank you,

Mike
