Ok, actually this is a question. Back in Freshman and Sophomore year of high school I took a power shop and a metal shop class. Well the first year we worked on small engines, and the second year we stepped up to rebuilding VW bug engines and reworking the points on an old 350 Chevy...

During the first year, when I was rebuilding my Briggs, the valves were carboned up and mildly burnt (35 year old lawnmower engine). So we took them out and set them up in a drill press. Turned the press on made sure it was straight, and the worked the valve with some sandpaper (actually, it was this other stuff ment for metal, it was black, I can't remember the name right now).... anyway after a couple class periods my valves were all set. We lapped 'em in there and was done with it.

My question is, can you do that to automotive valves? Would it be worth it? Would it work?

 

don't try it, it'll mess up the valves and be a waste of time, if anything just lap the valves.

ditto that, theres a big diffrence between a brigs and stratton lawnmower engine and a car engine, just take the heads to a shop, spend the 150$ and know there done right.,

 

Thanks guys...
