Problem, work your diagnostic acumen

Hi Folks,

	I need you're collective wisdom and theories.

Here's the situation:
At the track yesterday the car suffered from the following
Getting hot too fast and then nearly overheating when 72 outside..fan on 
full
Losing major power in the high RPM ranges.
Suffering bad gas mileage today especially at high speed
Notice cap on manifold test pipe was blown off.

I have a theory, but would like to see what you think so I don't color your 
opinion.  Also, I think I need to do the lifters...bad sounds eminating. 
 Has anyone done this?  If so, what can I expect to pay?

Thanks,
Please reply ASAP to paulroyal@mediaone.net
