I agree on head bolts also, don't buy OEM. When thinking about my own motor my biggest fear is leaking between the head and the block. I have bad dreams at night, wake up in cold sweats, sometimes I pee a little, it's not good. If anti-freeze gets in your crankcase kiss all your work on the bottom end goodbuy. One question though, do you have all the parts to turbo it yet? Just wondering because if it was me I would spend my money on building the head so I only had to pull the motor once. I know its possible to pull the head with the block still in the car but I've done it and it is a bitch not to mention you could break in your engine a couple thousand miles before the turbo. Also what compression are your pistons, did you drop to a high 8? Of course all these things I say are just in my humble opinion and I'm way looking forward to pictures and how this build goes! Good luck man.
