I have already accounted for this in a conversation with Delta.

I had a torque grind applied to my cam, which takes approx .030" off the cam lobe.

In my removing .030" off my head/block surface, I have minimal adjustments to be made to my valvetrain ;)

My biggest monster is going to be the intake. Which may be getting cut down to fit with some custom piping, or I may just make a custom manifold.

 

But thank you for the reminder :)

Also, on break in, I already have break in oil in mind. I'll be switching to Schaffer's once Its all broken in and happy.

no ned to oval the inlet to head holes, unless you have an oval hole drill :) - just a larger diameter round drill bit in each hole both ends, makes a big difference

I'm going to oval them with a same sized drill bit as the hole, just grinding out the side that needs more space. That way I only have one plane to worry about when remounting rather than multiple.

PS: Or I may just build a custom intake using my old manifold.

Unfortunately I don't know anything about them.The engine was in the back of a vehicle I bought.I had the heads off because I was going to change the headgaskets and run it but while it was apart I managed to loose about 1/2 the bolts/nuts/and pushrods,I suppose that is what I get for building an engine in my driveway.So I decided just to get an EJ22 and not even worry about the EA71. The bores looked very good when I had the heads.I tilted the engine up on the side and poured a bit of oil into the bores and it seemed to stay on top of the pistons so it shouldn't leak much.
