Right im in the process of sorting the head gaskets going ok so far apart from a couple of stubborn bolts. When taking the plenum chamber off and inlet manifold the bolts were just hand tight ( I think someone has rushed a job) took valley gasket off( that had silicone sealer all over it. Now on taking the rocker covers off I was a bit puzzled look at the pics and can anyone hazard a guess on why the colour difference.

i just did mine. i would say some ones replaced the head on the left prob due to being porous. the head on the right is the same colour as the valley so original.

simples n good luck with it

Well I wasn't going to say anything but I was thinking it may have been replaced. Just hoping I don't find any more nastys when I get the heads off!! those heat shields are a right pain aren't they. Don't think ill be putting them back might put exhaust wrap on them instead

so pic 1 im decoking my heads and lapping the valves seats i also replaced the valve stem oil seals, these are replacement heads i bought i had them pressure tested and skimmed

pic 2 i heat wrapped the manifolds no point in refitting the heat sheilds they were a pita to remove and some of the captive nuts broke away

pic 3 my heads are on i resprayed the rocker covers after i cleaned them up

everything works as it should iv got to replace 1 rocker at some time but thats enought fiddling for now

where did you get the exhaust wrap from and how much did you need. How many times did you wrap it round (ive never used exhaust wrap before).
