Just a quickie here. Does anyone know of any compatability issues of fitting a later ('93) c20xe head on an older block ('90 ish), such as oilways or water ways not lining up correctly, or any other problems I may encounter?
As Trevor says, heads will pysically fit on and so will manifolds etc, but there is a screw/bolt hole on the later 1993 > heads for the DIS unit, the early < 1993 heads don't have this. But in your case, this shouldn't be a problem as your using a mechincal dizzy?
Thanks for the replies everyone, time to rip it off tomorrow. Another question, does anyone know who does a complete hose kit for a cav gsi other than vauxhall as I have to replace every hose due to a pourus head problem?
