xe cylinder head work
im going to be rebuilding my engine and while the head is off i was thinking about getting it skimmed polished and the valves re seated is it worth getting more done like ported and big inlet valves im interested to see what others have done its just going to be a for a track car
what intake setup have you got? ie ITB's or standard (that includes any fagging air filter gheyness)
What cams are you running?
What engine management are you running (std inc "remap" or aftermarket)
if you are goin to modify any standard head, make sure u do it to a coscast one and not a gm head, just incase it goes porous!
excellent use of a spam post there
the KS heads are fine as they DONT go porous for a start, and the crack that occurs is easily fixable.. or rather I'd do the fix while the head is off before the head gets chance to crack. Job done and no need to pay the stupid rates for a coscast head.
where does the crack occur im taking the head off this week i will look for it
hope youve got xray specs

stuart you are a legend m8 thanks im going to get the head preasure tested this week. forgot to say the engine is standard cams and management for now thinking about getting the cams reprofiled and have been offered a set of 45s with manifold.
Id get a basic "port" job done if its cheap enough... ie take out any casting lines, tidy things up and generally make it a bit better, without making it a PITA with regards to the std mangement etc
If I had an XE and it was in bits, I'd get the fix done regardless of if it had cracked :D
I think JonLem on mig (maybe here too) did an alternative fix to that link, but I couldnt find it in searches.
ok it was Joff

cheers again stuart while the head if off i will give that a go p.s is a loss of compression on number 3 cylinder (common)
erm.... got pics of the gasket and head face? it might be a simple gasket failiure, or something like head warping if it got hot.
