When rebuilding your engine you need the proper tools to do the job right. Don't listen to your friends when they tell you that you can use your fingers to compress piston rings, get a piston ring compressor. If you have any old baked on gasket material get some good gasket remover spray to make it a little easier scraping off the old gasket. And don't forget a good torque wrench when putting that engine back together. Save time, save headaches, use the right tools!
