Re: If youve had questions about integral vs. non-integral head inline 6's w/pics

well, as far as I know and after reading Leo Santucci's book on performance modifications on theinline 6's, there is minimal if any difference between cylinder heads for these engines even though the casting numbers vary. As far as I know they all had 1.72 dia intake valves and 1.50 exhaust valves... and flow the same. Also all of the non-integrated head off of a 230-250-292 will bolt on... There is a small chanber version that came in some early cars, but the odds of stumbling into one of those would be unlikely and it will still bolt on and function well on your engine.

Anyway, I wouldnt go spending a ton of money on a head from one of those shops, as im sure there are some board members near you that may have a perfectly good head laying around that wont cost you much. I have a good head here in my autoshop, but Im sure the shippping would be cost prohibitive from northern MN. I can look into it if you would like though. I have magnafluxing capabilitys here at school and it is crack free. I could also touch up the valves and seats.

In the end, with the cracking on your head I wouldnt bother with it and Id look at a rreplacement.

Hope that helps
