2000 exhaust manifold on 7120

Post by amceaglesx4 » May 20th, 2016, 6:23 am

Do theses bolt up to the 0331 head and possible better flow better than the single outlet. I curious due to the fact of a possible true dual exhaust on the Eagle.

The 2000+ dual cast manifolds don't properly cover the larger exhaust ports on the earlier 7120 or 0630 heads.

I have swapped a few older 0630 heads in place of the 0331 head and is easy and no issue with the smaller exhaust ports and a simple seal is either to buy an adapter plate that I know someone makes just can not remember who or what I have done is just double the gasket using one 0630 and one 0331 and it seals up great...
So if you want the 7120 head just sub in the gasket that matches and I am sure you'd be fine...

How's the double gasket holding up? I've been informed that using a 0630 head with a 00 and up banks torque tube header will cover the gaps, but also wanted to know if this is a good alternative.

The double gasket holds up very well and Never had one returned with any issues...
