Andy,
DC-19 cam was recommended to me by John Dougherty as the most agressive cam I should consider for my application. In comparing profiles, the DC-19 is identical in all advertised areas except for a slight increase in I/E lift values and a variation in valve timing. What would be the defining performance difference between these two cams. Also, how does the 20/21 cam caompare to these two?
Mike(MBEngineering),
I've not had any success so far locating a suitable replacement for the damaged head, so I may be faced with repairing the one I have. That's the trouble with having somewhat desireable limited production parts, its like having a rare blood type, kind of cool until you need some....

....excellent advice though, and if I'm fortunate enough to locate another head, I'll certainly recheck and adjust deck height accordingly.
Thank you both for the feedback.
Mike...
