Im genuinely struggling to work out wtf FNQ is on about....
I wasnt sure, so thought about it for a bit, forgot about it, TK answered, all was good, then suddenly we have a novel that doesnt come close to the actual question?
Dave has an interesting Q.
I have def seen similar with non LPG heads though.
Holden six cylinder head 101.

sorry to sunburst and to bomber regarding the confusion. I was trying to quote some statements sunsburst made but somehow the formatting got lost and then i recopied it a few more times for absolute confusion!!!. ( don;t ask me how)
My point was a forum sometimes includes not so good info as well as the good. ( Not always a good thing but not always side tracks for no reasons)
Too early Sunday morning, for me to be posting

Don't panic Darryl, plenty of others post confusing comments & i write like a 5 year old @ that time of the morning too ! I think Jas got his answer from Tony, so all is good now. It's part of any public forum to get some speculation & assumptions & unfortunately usually when you need a definitive answer. Gary.

The colour of your exhaust valves is typical of leaded petrol. The leaner the mixture the whiter the colour.

Finally found the part number after looking though all the parts manuals HQ-HZ and LJ-UC , it is in the LC manual
Was thinking LC didn't have bridge rockers
Anyone with a LC with a 173 that can confirm the machining is not suppose to be there ?

It's not supposed to be there.
It's been machined to decrease compression.

929 is a standard HQ-HJ thus HG and LC 173/2850 head. They should just about all have non adjustable rockers.
