Your best bet is the Yella Terra YT6309's. They are made specifically for the EFI heads, are bolt on (so easy as pie) and are adjustable should you change pushrods in the future.

These are the ones fitted up to my car, made it a dream to drive and added around 5rwkw. I really need to finalise that write up aswell!

Not really pumba. Once they are set you shouldn't have to do them again, unless you make changes to the valvetrain set up.
the Non adjustable Street terra's are $574 and the adjustable Yella Terra's are $898. but both are very popular and stocked and lots of places so it would pay to shop around.

Umm, please excuse my ignorance, but what is the difference between Adjustable and Non adjustable - is there any advantages and/or gains between the two???

i ended up going with a set of street terra non-adjustable rockers. worked a treat,and revs alot more freely now.

i cant answer that one pete, but it is an interesting question...

Adjustable cost more, need more valve cover clearance and can be used with solid camshafts. They can be used to compensate for variations in valve height after reco or modifications to the heads and so are popular with engine reconditioners.

Non adjustables are cheaper, less complicated to fit and set up, in most cases clear the stock covers but can only be used with hydraulic cams, and heads (valve heights) need to be within tolerances.
