383 knowledge anyone?

The MP Eddys I can get from www.mopartsracing.com correct? How big of a change would it be to add nitrous? Lower the compression, cam and such I know possibly. But anything with the heads?

I heard that if I run a solid roller that it will wear down due to me taking it to shows and such. Is this true or just a bunch of junk? What lifters and cam do you recommend?

Carb size I should be looking for about 950 - 1050?

Whats all the things I should look at and consider on the oiling system?

Thanks Mguner, I will look at the tri holley carbs but right now I would like the manifold just fine.
