Thanks guys for your replies...in response to your comments about the valve being bent.

1) wouldn't the negine make noise as soon as the engine starts w/ a bent valve.

2) I also wrote the timing procedure kinda wierd on the previos post. I meant to say that I drooped the dizzy in w/ the timing tape reading 8 degrees BTDC and when I fired the engine it read between 5 and 10 AFTER TDC. The engine was idling at around 600 rpm and running a little rough so advanced the dizzy to 13 BTDC and it ran great for 15 minutes until I messed w/ the mixture screws.

3) I'm running a Edelbrock EPS idle to 5500 intake w/ aluminum aftermarket heads w/ 2.02- 1.60 valves
