ok I went to the track yesterday and my car hesitates real bad at high rpm, my valve spring are binding, I have a set of 243 heads in the garage.

WILL the springs from the 243 heads work on my stock ls1 heads with my stock cam??

I know it sound weird but im trying to see how fast I can go with stock heads/cam..

went 10.5 @ 128 yesterday

Yes, check installed heights though to see if its really binding. Binding is bad. Like blow up your engine bad.

how do I find out if that's what its doing? it don't do it on the motor pass only when I spray it

watch my run at the end of this, if you listen closely right when im passing the finish line you can hear it hesitating, its not the rev limiter we turned that up high
