With all the spirted bickering going on and before the heat gets turned on between parties, please be reminded that all that has been said over the last day is completely off base in term to what the OE poster put up.
Which is a very general thought.
So far, he has brought up the possible use of 2 very different engine and only mentions a very small amount of parts to be used, or so he thinks. (Thats what I gather, anywhoooo)
If you all start this battle between which head is better, both parties are up crap creek for *Thinking* they know the answer to a question put forth that is to vauge to truly answer.
The only answer worth considering is the "In general opinion" answer, much like what Moper gave. It's a very broad and in general opinion on how such heads could be used.
Conduct yourself nicely please. I know certain issues/threads topic are just great for banter and other bologna.
