Re: curious about holes in exhaust port area of head
yea... at work so don't have a pic. sorry.
But if you were looking through the exhaust side header hole into the head you would see to the upper right of where the valve guide is(or left depending on which cylinder), a small sorta rectangular shaped cut out. That recessed cutout goes back into the head and comes out as about a 1/4inch round hole where the head meets the block. In their dirty state.. it's hard to think of them as anything more than just a funky cutout in the aluminum.
