I know this is a Holden forum but hoping there are some people on here who can help so I don't have to join the Ford forum.........

My daughter's partner used to be a die-hard Ford fan (went to Bathurst most years with his dad) but is being converted by our Holden family, particularly my daughter's VYII SS he often drives.

However, he does have an AUIII XR8 (2002 build) which apparently needs new valve springs and rockers. Unfortunately it's one of the "hand built" Tickford motors. Even with my contacts the valve springs are going to cost around $550 (TAU36513A & TAU36513B, 8 of each) and the rockers are over $2000!! (TAU36564AKT)

I aim to get some from the USA but have no idea what parts to get in their place. Am hoping someone can please tell me what parts I can use in their place. Also, apparently the head gaskets are no longer available and standard head gaskets I've been told are no good as the Tickford motors are higher compression than normal.

Heeeeeeeeelp!!

Thanks,
Gary
