Ls2 with harrop 122 charger fitted Hello people.
I'm located in Yorkshire, United Kingdom.
Have a Holden HSV R8 (2007 Wortec Carbon Edition). It's got a 6.0 LS2 fitted with a Harrop 122 supercharger. Running around 640bhp.
Would like to find out more about the engine, so figured here is a good place to start!
Think there is a noticeable noise coming from the rockers / rocker shafts. The vehicle has covered around 82,000 miles. I've owned it for a few months now and it's all been fine (besides developing this noise over the last week or so).
A good family friend who has worked on all sorts of high performance motors over the years will be taking a look next week. He's advised me to look into sourcing some new rockers / rocker shafts. I've had a look round and found the high ratio SLP rockers. These can be bought in the UK for around £650, or imported from the USA for around £370. I'll know next week if I'll need to buy these or try and find some standard rockers somewhere else.
A quick question I have is can you fit LS3 / LS7 heads straight onto this engine and if so, what other bits would need changing? Is the fact is Supercharged going to matter?
PLEASE forgive my ignorance, I'm fairly new to all this! I do learn quickly though.
Thanks in advance!

More than likely your rockers are fine. You probably have a lifter that is starting to go out on you. Just dont replace your lifters with LS7's they have been having a bad reputation with failing.

Where is a good place to buy lifters? It's not too easy getting parts in the UK so would probably need somewhere in the USA that will ship to the United Kingdom.
Thanks again.

Ok,
I've removed the rocker cover to find a 'wobbly' rocker. Swapped it for a new one and still having the same issues. It must be a lifter as the spring seems ok.
Does a lifter going on its way out cause any other damage or harm to the block / other parts?
Thanks again!
