You can bring the heads to a machine sop and get the bottom of the heads resurfaced. They usually take like .010 off to ensure flatness.



You may as well get a good set of roller rockers for the price of the modded. I noticed ZZP had added a 50.00 deposit. Wich makes them almost the cost of some Yella terra roller rockers.


As for getting the gasket off i would use a wire brush on a drill and be real carefull around the cylinders.Make sure you clean everything EXTRA good.



You'll need to take it to the machine shop if you get bigger valves. And don't get the valves with the undercut stems. They have a reputation for breaking.
I'll say this before I post this. I worked at an automotive machine shop and still do some automotive machine work.

Do not use a wire wheel on a drill if you have ever surfaced a head you would know why. It creates all sorts of high and low areas. A better way is a single edge razor blade scraper. As far as the surfacing goes no good machine shop would ever go and just blindly remove .010. You remove only what you need to. I'm not picking on the poster buy qouting him I'm just correcting some mis information. Now there are a couple ways to see if the valve are sealing with the heads off the engine, you can use a vacuum pressure tester which I doubt you have but a machine shop will. The old stand by way that tons of home mechanics still use and works well is fill the ports in the heads with thinner and watch to see if it leaks out. Your old valves and seats may need reground which is something any machine shop should be able to do.
