Finally got my block on Friday, waiting on gaskets and bearings but I decided to pull the trigger on getting my head ported.

Looks awesome! I see the channels milled into the top of the sleeves, did you say what type of head gasket you're going to run? Also, I can't remember, did you have that block re-sleaved as well or just closed deck?

Hi, there,
I have a question following a discussion I had with a friend.
Is it possible to use the s55 engine block on a car equipped with the N55?
What seems compatible:
-mounting points, sensors (CKP, CMP),
-Engine sensors: several sensors, such as crankshaft, AAC, etc., are in the same locations.
-Lower housing, HPFP pump location and even cylinder head are very similar, though not identical.

Do you think this is a long-term solution?
