Two things that struck me as odd about this write up. I'm not trying to be a doubter or "hater" as some like to say, I would just like a little clarification. First off You said, "flow bench on the head", that doesn't make any sense. Did you mean you had it ported and they put it on a flow bench to see the numbers, if so then what were the numbers. You can put any head on a flow bench to see how much they flow at different atmospheres of pressure but it doesn't do anything for performance, it's just a test. Second you say you took it out 3mm to 87mm yet I didn't see anything about the block being sleeved. You say you have a block guard but not sleeves. You can not bore that block out to 87mm without sleeves. A little clarification on these two things would be nice and also if you have some pictures. What engine management are you using to tune with? With the build you have described that is a big budget build why not go with a Hytech or Burns or RMF header. Surely you know that on a high horsepower all motor application the header is the crowning jewel that can really have a great deal of affect on your motors performance. You speak of it as if it's a part you are just going to throw on at the end. Comptech header on that type of build? You need to step it up a notch if that's what you are planning. Good luck tho, I'm interested to see some type of pictures, dyno's, proof.
