Is the 3.9L engine in the same family as the standard 3.5L Buick aluminum engine? I was told by a rep at Hedman that they were commonly used in these vehicles for many years. He said if my 3.9L is in the same family, then they sell headers (PN 39800) that will definitely fit the RRC.

So, how does one know if the 3.9L RRC engine is from the same family as the standard 3.5L buick aluminum engine??

The Rover V-8 started as the Buick aluminum 215 cu. in. V-8. You can read some of the history on Wikipedia here: http://en.wikipedia.org/wiki/Rover_V8_engine.

I met a local guy who put a 3.9 in his wife's MGB. He used an Edelbrock intake manifold for the Buick 215 and a Holley 4-barrel. I think he used the iron exhaust manifolds, since they flow very well.

yeah, i saw the wikipedia info.....but wikipedia is not the greatest source of information to cite as anyone can log in and edit the details. wikipedia can be used to find references (or additional leads) that direct you to additional sources of information. i figured you guys havent led me astray thus far - and i was correct, again. thanks for the confirmation!

Perhaps you can get gaskets from him and see if they line up. Alternately, if the rep is not in Qatar, it might be less costly for you to order some RV8 gaskets from a source local to the rep to be shipped directly to him to compare.

I'm guessing the gaskets made for the headers are going to be the best bet.
