    Most economical way to clean a20A3 Head/Block Surface...

    Hey guys, anyone have any idea of the most economical way to clean the head and block before reinstalling the head gasket on my '88 LX-i? Assume no tools, all I have are wrenches and a chain... I have the head on my balcony on a table, with the exhaust and intake manifolds removed, ready for their new seals, but still dirty/carbony as crap... Thanks...

    Plus they will check for warpage, which, if you blew a headgasket is a very good possibility.

    The most economical way to clean the head and block is to use a few razor blades to clean off the old gasket material.

    As everyone else has suggested having a machine shop check the head is a good idea. Around here for less than $100 you get a head cleaned and leak tested and the deck machined. When you consider what another head gasket and your time costs if the head does have a problem it seems like the easy choice to me.
