New Shortblock, Same OEM Head... Need to be resurfaced?

[Alpha]

Hey guys, I had a sleeved and forged shortblock built with great internals and decided to keep the stock head since I'll be on stock injectors and didn't feel the need to work the head.

My question is, does the head need to be resurfaced before going on the new block? The car/head has 83k miles on it.

The reason I'm asking is because we swapped the shortblocks/new head gasket over and have been having nothing but problems ever since without milling the head.

Overheating, air in the cooling system, and now exhaust gases in the cooling system (Surely due to a leaking head gasket) with only 45 miles on the car.

I just wanted to know if this is mandatory/common sense or practice or if my problem lies elsewhere.

Thanks in advance,
Alpha

No.

yes, always have it checked and resurfaced if needed

Having a leaking head gasket with only 45 unboosted miles on it definitely makes me think it wasn't square. Damn : (

Seconded. They're aluminum heads, take no chances. You should have the deck checked when you pull the head off this time, too.

Should always be checked, what kind of head gasket / bolts/studs were used?

You likely know, but don't run it, if exhaust/air is getting into the coolant, you might/will have coolant in oil or coolant sufficient to hydro your shiny built block.



But it isn't respectable. It's mildly terrifying. And that actually makes it quite appealing. - Mazda 3 MPS review, Matthew Jones, Top Gear.
