Yeah, I went the Manley with the dual thrust option, as it made more sense. I can't for the life of me remember who quoted me that price though as it was a few years ago now. If you talk to Danny at performance mods, he won't even do the conversion as its too much stuffing around apparently? Maybe he doesn't have the correct tooling or machines?

I can't remember what I paid for the machining for the 14mm studs, but when you factor in the cost of the studs + machining the block & heads, it makes more sense to get the aged hardened ARP ones. Unless your planning on 40+ pounds of boost into it. My personal opinion is the ARP's will get the same result at a cheaper price.

I'll get the guys info who did my studs in the block.

One thing you have to keep in mind, is that Perth is very small in comparison to the UK, so the necessity to complete some of these more intricate tasks is not really here, hence the higher pricing as everything takes longer, due to the experience level & how many times they have completed the task before.
