Rite-o cheers lads. Think i'm going to have to stop trying to figure it out as i'm either going to drive myself crazy or end up messing the engine up lol. I'll just use it as said above that the engine is healthy and ready for modding.
Only thing i'm going to look at is what Cams are already in the car, but that won't be until I go about fitting my new 135's.
