Check your lifter preload.

 

well how do u do that .i know it sounds dumb but hey thats why im not a mechanic... lol.. , i used my stock lifters if that help on anything

 

Your rockers are too tight, loosen them up.

If you don't know what he's talking about with lifter preload then that indicates what the problem could be. If you adjust the valves too loosely you'll get all sorts of noise from the extra clearance and lower power output. Too tight and the car runs poorly and you run the danger of burning valves because they don't close. Here's a link to show you how to adjust the valves....

Don't bother with the engine running method. It's just messy and isn't going to give you much over a non running method.

Ask questions if you run into trouble...

Good luck!
