Yes, the extra cubes will complement the head work and cam, we take the stock cylinders to 98" more often than 95" but offer both. No negative issues either way. One cube usually equals one torque or horse on a mild build.wanting to have my heads ported and polished and add a nice cam this winter on my 03 ultra. was thinking about goin to 95 as well. what would would be the difference in an 88 verse 95 with the same engine mods?..is it worth the extra $$ goin 95 in.?
