@rayfire50 I hope so.

im pritty hands on and like to jump in, but not being funny but id rather pay a small fee and have someone do it with the correct kit as if you do this method wrong you can have uneaven ware or maybe even go too deep and have the valves tapping on your piston, if you wanna risk it then be my guest! thanks for the vid, good idea none the less!

Untrue. Aluminum heads are crack prone, especially between close valves, like all modern multivalve engines. Warpage has more to do with the length of the head than the material from which it's made. Ask mechanics about 5-cylinder Volvos & warpage! When you curb a steel wheel, it bends. When you curb an aluminum wheel it cracks or shatters. When you said "The aluminum alloy is very hard" you couldn't be further from the truth. The aluminum pistons are far harder than this head.

@TonyWilliamsFever Saves money on sandpaper and glass tables too! Thanks for the chuckle.

@BuBliEz4 If they weren't warped or twisted, then they were flat when you started and all you needed to do was clean up the head gasket surface a bit.

@zapwatt Zap knows what's up. And in reference to my first comment, keeping the bottom of the head parallel to the top is key.

@BuBliEz4 I don't doubt you can get away with this. Engines will run under all sorts of less than optimal conditions. I don't advocate milling the head every time either, because it has been aptly pointed out that if you restrain it to a mill table and fly cut it, then let it go it might have a warp to it and when you bolt it on the block now your camshaft could bind.

@kylebilyard I can assure you I would never let you touch anything I own.

@BuBliEz4 ..I'm always dubious about using an outside workshop, they often talk a good job, but......then there are the good ones, but knowing my luck...I have the tools to do this job properly, and have machined industrial components to 0.0002", in temp controlled environment, but I have also done this to small heads in the past, maintaining flatness & squareness with good results. Its all relative really, and down to the operators skill in setting up and operating the process.

what about final compression ratio? ended up being equal in all cylinders?
