Compare Dove Heads To Other Manufacture's ?

[BattlestarGalactic]

My tunnelwedge is Dove #057.  I bought it new a real long time.  It resides in the wagon.  Never a problem.

A friend bought one back in late 90's.  It leaked like a sprinkler.   He ended up having it powder coated to help seal it up.  As far as I know it is still in use.

Did he generally stay with the same valve size and what were they ?

Very few people install valves in the intake manifold.

I've done that a couple times - but never on purpose

I have 3 sets of Dove heads, and the casting quality varies greatly. The C4AE-F high risers leak check great, look good with no porosity, and have no issues. The other sets are raised and relocated exhausts with raised intakes and they have pinhole leaks from porosity. I've worked with a set of Raised intake and exhaust std loc and they were unmanageable and castings so dirty they would not take weld. Scarfing out an area the size of a golf ball and welding up proved futile as the casting had so much sand in it. Bottom line is that they are not for the faint of heart. They can produce some fabulous numbers but are questionable quality. If you want a set with no fiddling, go elsewhere.
