Hard to tell if they are raised exhaust port like my Indy EZs. In fact they look similar to the Indy's. hope it works out for your agency Neil. That is definitely one of your top areas of expertise.

Not yet   , no flow #s either not sure why they all seem to offer 84 cc rather than 78-80 so you effectively replace the head & maintain the compression ratio / heat . So far the Bulldog is the best head I have seen with 78cc chambers & heart shape around the valves & swirl flow all for a reasonable price but they unfortunatly did not last long .

Why did Bulldog not last?

1999 Trans Am, LS1, heads, cam, headers, stall, etc! Love to surprise the rice rockets with this one. They seem so confident, then it's "what the heck just happened?"

High cost to tool them & no advertising budget I assume , I got 2 sets & had a shot at a set at a swap meet once , thought about it too long & someone grabbed them before I got there . If I had deep pockets I would pick up where Bulldog left off & do a street version & a raised port max effort head

It states on the web site the exhaust ports are std / stock position , I have asked what advantages exist over Eddy or 440 Source heads

 :iagree:
 Not a whole lot different than stock? A picture of the combustion chamber would be nice. In their picture the exhaust runners look like they have a core shift issue? :dunno:   The runner volumes are nothing to  get excited about. That's why I went with the Mopar stage 6.. for the raised intake runners. I then raised them an additional .200" beyond that.

I went with Stage VI, because in 2000, that's about all there was, other than Indy. Now there seems to be
so much more to choose from.
