I was at MSL again today for some upgrade work namely SLS valve buckets, ARP Cam phaser bolts and ARP head studs.
A lot of fiddly work especially resetting the timing and to get it spot on, hats off to Adrian who had it spot on with the first attempt.
But all in all a good days works just to put my mind at ease, now I was pretty sceptical with regards to the head bolts issue with so little failures for the number of units out there I was in 2 minds to go ahead, but with the level of power I run I aired on the side of caution.
Now I'm not sure if its age or because of the stress my modified engine puts on the head bolts but my cars up to 23000 miles and is 4 years old its done approx. 2000 miles on the supercharger and very few on the Nos so I was quite alarmed at the level of corrosion on the head bolts, it is easy to see how they fail!!!
As for the phaser bolts the new ARP ones are stronger than the stock ones but there were no visible signs of excessive wear, damage or corrosion on the existing bolts and the same for the valve buckets but those head bolts were really something else.
Hats off and another BIG thank you from me to MSL, who with the help of forum members keep pushing envelopes, experimenting and getting ever closer to results that Acid and the team strive for

These are a selection of the existing head bolts some were not as bad as these but the majority were similar.
The head bolts were replaced with the ARP head studs by changing one at a time and torqueing down before moving on.
