I have a chance to get a hydro head for my car. The good part (maybe) is that it is polished and ported. The bad part (I think) is that it measures 131.84 mm. My bentley says the minimum head thickness should be 132.6 mm. Should I just pass on this? I was going to put it on my ABA block. -- Kervin 80 1.7 8v Ole Paul 82 1.7 8v The gift 86 2.0 8v no knock sensor yet 00 tt600
