Hey, looking to buy one of the larger displacement mini's within the next few months but due to them being so old I know I'm going to run into some problems due to excessive wear when it comes to the engine, suspension and rust. Was looking up the costs of a few things like resurfacing a warped head when I found a video of someone sanding his heads flat (). This seems really sketchy but apparently is used to be the normal when it came to warped heads and a bit of elbow grease never hurt anyone, but the biggest problem I can see is that wouldn't having your sparkplugs 0.004" further down the cylinder change the ignition timing and mess with how the flame front works? At what point would it be better to just buy a new head? Would be nice to know that this method works so that buying a cheaper mini with a warped head issue wouldn't be off the table. Thanks.
