How much will these headers hurt my small block?

Stock magnum 360 long block, cam and all. Dual plane intake, carter 750, thats all thats done to it. In an a body with a 28" tire and 4.10 gear. I have 1 5/8" hooker comps on it now and it runs good, but the headers are about shot. I have a set of tubular automotive 1 7/8 x 3.5" headers that I'd like to set-up and use. I know the combo is all sorts of wrong, but will it make that much of a noticeable different from the smaller tubes?
I eventually plan on doing a head and cam upgrade. Thanks.

I know they are far from optimal, but about how much power loss are we talking? This motor currently is all in by 5k... lol dang deisel.
Another header question, will the slip fit tubes be leaky if used with an actual exhaust? Seems like they very well could with the back pressure... ?

Hard to say how much power you would loose... on the slip fit, they are pretty decent fit(or they should be) and after a short time they tend to seal up even better (rust and or carbon)

Is it common practice to use any type of sealer or anything on these type of joints?
The exhaust is just 2.5" w/ chambered mufflers dumped at the axle.

i never used any sealer on the slipjoint on my TTI headers and they have been sealing up perfectly, this was with 3" exhaust and some diferent mufflers but no problems keeping it sealed!

Chambered mufflers cause back pressure and therefore may cause your slipjoints to leak. I would toss those in favor of a good flowthrough muffler.
