Header/intake

[89Sunny]

This might be a dumb question BUT do I need to take off the intake to take off and replace the header?

I would, easier to work on and you need a new gasket anyway.

 

Get a foam rubber filter on there before you suck that sound deadner into the engine.

[89Sunny]

Thanks. I didn't even think to pick up a new gasket.

 

That's an older picture I've put on a newer air filter since then.

if your stock exhaust manifold is bad I would take off both.

If your putting on a cheap header thinking your going to go FASTER your waisting your time and reliability of the car for such a minute gain and I mean minute gain by putting on a header on a 35hp motor if that.. Unless its Ceramic Coated also.

I say don't do it!!!!!!!!!!!!!!!!!!!!!!!!!! if your set up is fine as it is and works.

He said replace the header. He might mean the exhaust manifold which is pretty close to being a cast iron header anyway.

There is a header on there now. The issue with the one that is that the way it's built is hangs way too low. My truck is lowered already and I'd like to go lower. So the new header (which was cheaper than a exhaust manifold) will allow me to adjust/move the pipe up and over some. I have no aspirations of going fast with the current engine.

Would not a stock exhaust manifold be better, then you can put the exhaust where you want it.

Probably but I did no/do not have one and the ones I found were at least $100 more than the header.

It's just an A series exhaust manifold isn't it???? They throw them away. Try a want ad here... https://ratsun.net/classifieds/category/9-datsun-parts/

I see tubes in this pic. Looks like a header to me.

[banzai510(hainz)]

order a A SERIES GASKET AND YOULL BE ABLE TO FIGURE THIS OUT IF YOU NEED TO REVOVE BOTH BUT 99% best to get a new gasket and a good one at that while running a header

That manifold is a pile of crap.  Notice the siamesed center runners and the 4-into-1 collector? The early ones were much better.

He mentioned he was not looking to go fast, so I posted a photo of a stock type manifold with the single head pipe that would make it much easier for exhaust routing on a lowered vehicle, there is more needed to make that exhaust manifold work as it is an emissions manifold with at least 3 holes in it that need to be plugged.

[Stoffregen Motorsports]

Right. It will do that for sure.

 

I just feel like if I'm going to take the time to swap it out, I may as well spend the extra hundred bucks to get a good manifold.
