Hello everybody, i am new to this forum (as you could see from my post count), however. I've been looking for quite a while now for information regarding building heads and blocks for d-series. I am looking to set up a project for next summer (if i get my car running this summer and end up not selling it). and i would like to build a z6 to handle some good 400whp. The build needs to handle this amount, even tho, it doesn't mean that it will have this amount on it. Looking for information regarding step by step procedures on block and cylinder heads assembly. Torque numbers, tips that might be useful, things to look out for, etc. Any help would be really appreciated, thanks in advance.
