Another thing I had not really given much thought to prior to the build, which head studs to go for? More choice than I was expecting and fair to say a wide price range too. The ones which came out were all in decent condition and could have possibly gone back in. Like for like was a definite option as were slightly cheaper alternatives. In the end though I decided on the ARP replacements. All reviews of these studs were favourable so I took a deep breath and said yes to these shiny beauties that no-one will ever see but I know they are there. A bit of bling!
