Well, I don't really plan on seeing a ton of HP out of this, I just want, as you said, a more streetable motor. The bottom end isn't going to end up with a lot of attention. Just new rod bearings and such. A bottom end job isn't easy to do with the block in the car. Not around here anyways. It's got 200K+ miles, so it will see it soon whether I do it now or not.

The 4-2-1 was my original thought. I was going to cut the stock mani and build off of it, or just try and find another one to screw with. I like lots of torque ;)

Id go a 4-2-1 extractor aswell. with the right cam grind and the weber and good spark you should have a very tourqey a series that will drive verry nicely.

You're not going to see much of an increase in hp with the mods you have described but you will end up with a very usable street motor.
Strong accurate spark - you have done.
Refresh the head as you have planned - don't worry about stronger valve springs as the factory springs are fine for 6500.
Re-ground cam will be fine.

Not sure if you have plans to tidy up the bottom end but I would try and do that if you want a 0 hour motor with no weak spots.

I'm in the process of building up my A15 in my Sunny, and I need to know some opinions on this. I'm working off a low budget, so any advice on how to save money would be appreciated. The plan is to build a decent amount of N/A horsepower.

-So far, I've killed all the emissions and installed a new MSD Blaster 3 coil on my electronic dizzy. I got a 32/36 Weber DGAV to install as well as plans on the drawing board for a custom header based off my stock exhaust manifold and glasspack to finish it off.

-As far as valve train, what should I look for? I'm planning on pulling the head this summer and rebuilding the head, lapping the valves, new valve seals, etc. Should I consider stronger valve springs as well? Or are the stock one's okay on an N/A engine? I don't really plan on revving beyond 6500

-What are your opinion's on re-ground cams over new cams? I know I can save a ton of money by having a cam reground instead of buying a new cam.

-I need to try and avoid pulling the engine. I have too many problems as is with the county code enforcement, and I can't risk any violation's. Pulling the engine would draw a little too much attention.

Sorry about all the questions, I'm kind of a noob when it comes down to A-series and I don't want to kill anything.
