I have heard instances where the 3 volt style worked its way loose.
I can speak from experience that the single volt style worked flawless for the 18 years I have used it.
The biggest negative is the work required to make it work on a stock cover. It’s almost impossible to modify and weld the cover without warping the area around the oil pump and oil pump shaft area. Better off using a Stage 2 cover and external pump. And if your going that far than may as well go to the Danny B setup.

I have the Milodon one, don't know which one it is. Modifing the cover is not that big of a deal. Friends of mine using chevys told me that their's would snap off the Cam Bolts. But Buick's have one big one.
I will give it a shot when I get there.
Thanks!

For all the problems it seems to bring, why don't you toss all of that in the trash and get a good quality true roller timing chain... 
... it will get the job done...

Claude I have to dis-agree on this one. For those like me and turbobitt using extremely hard springs the Gear Drive once properly installed is a good insurance. I am glad I just installed mine. I don't have to worry snapping the Chain at hi RPM.For all the problems it seems to bring, why don't you toss all of that in the trash and get a good quality true roller timing chain...

Joe... I understand what you're saying but it takes a lot to snap a good quality chain!... ( "good quality" is the key word here). I'm not saying that it can't happen but personally have never seen one snap... I've seen cars running into the low 8's with a chain...
Claude.
P.S: I have one on my big block Chevy (which was already there when I bought it) but I swear that if one day I have to take the engine apart for whatever reason, I'm taking it off and install a good (and more silent) chain.

the bolts in my gear drive where tack welded then where ground down flush with the back of the gear drive plate . im pretty sure they will not be going anywhere any time soon.

I don't have a definitive answer to that question. The heads were assembled by Zimmerman Racing and installed on a Stage 2 motor in a race car I bought. I have the paperwork for the engine but no specs were listed. Once removed they had a number of bent valves, I chose not to rebuild them as I had another set ready to run. As a guess I would say at least 250lbs on the seal and 550+ open.

I don't have the heads any longer, I gave them to Gene Fleury. I'll check to see if he ever pulled them apart.
