    I have an l98 with a large custom grind cam with standard heads, A guy near me has a set of ported ls3 heads for sale and was just wondering if these are an easy bolt on?

    Aren't L98 heads the same as LS3 heads? I thought they were both L92 heads.

    That's what i thought but apparently not, i rang the guy and he said that they won't fit as the ls3 has a larger bore.

    That's not correct as mentioned above both heads are L92 castings & do fit both engines.
