I've looked at some E7 porting articles and I have to say that in general the DOOEs i've ported are larger than ported E7s and I never hit water jackets. One article showed the width of the E7 intake port at the pushrod hole hump to be 0.9" after porting. Just for curiosity I made this same measurement on my heads and it was about 1.020". Bigger isn't always better, but if they only measured 0.9", the inlet would be a lot smaller.
