Gasket matching 782 Swirl head on the exhaust side?

Is it worth gasket matching the head on the exhaust ports? I already ported and matched the exhaust manifold so I'd assume I might as well do this but the ports get tiny 1" inside the head anyhow.

I'm not in the huge gains crowd, but a quicker spool up never hurt anyone.

Is it worth it?

Was planning on getting a 2.5" swing valve and down pipe. But due to $ constraints for now might just stick with the 2.25" swingvalve and exhaust. Other than open the exhaust up to a true 2.5 where it necks down over the rear axle, into a new muffler.

Thanks for any insight.

To quote Shadow, the big gains are to be had aft the Turbo.

Buying, modifying or building a better swingvalve is very beneficial.

I like to start with a 3" downpipe with no neck down, right off the Turbo.

3" downpipe, even with a 2.25" swingvalve has worked well for me.

Thanks
Randy

No donut, just a 3" pipe with a larger flange and stock attaching bolts and springs.

A talented muffler man friend made it for me and it never leaked.

Been running it for about 15 or more years.

Simplest and brilliant !!

Thanks
Randy
