Best engine rebuild kits?

I have a '68 Galaxie 390 ci 2brl carb. What is the best rebuild kit to get as far as performance and quallity?

Check out PAW or Summit Racing Equipment for good rebuild kits. PAW has a larger selection and you can customize the kits with equipment of your choice. Such as high performance cam, pistons, oil pump etc. Most come with a warranty of some kind and I have been happy with both Summit and PAW (performance automotive warehouse). Good luck. Steve
