I took my car to get tuned this weekend.

My results were decent, but I ran into some problems:

The valvetrain noise is extremely loud...excessively lound. The car pulls hard until 6000rpm, then the power curve levels off from 6000+. What do you think is the problem? Rocker arms not put on properly? Wrong length pushrods? Bad springs?

I would like some feedback of some things to try. Hopefully I can get this worked out.

Thanks for the help!

How did you set up the valve train? Did you verify geometry and pushrod length to get the correct preload?

 

what valve springs you got ?
