Gentlemen, I come to you from the dark side of 101 ownership to seek your wisdom on cylinder heads.
I am doing an engine build and have an offer of cylinder heads off a '97 disco. Bigger valves can only help the engine breath which can only help the green beastie pass emissions. Any power gains can only be good too.
I am aware of all the fun stuff to check on a used head. I am wondering, however, which years did Discoveries have the infamous sticky valves and what was done to remedy the problem? I know '96 had a problem but was curious when it went away.
Cheers
Gregor
