im about to buy these heads: http://texas-speed.com/shop/item.asp?itemid=84 . the spings that come with it, the prc double spring kit. are thes going to be good enough springs to intall the cam with these heads and not worry? 226/228 .585/.588 114 LSA is my cam size

 

more than good enough.

 

Yeah, they are good for .650 lift. I have these heads and felt a huge difference in top end power.

 

That cam is .585/.588 and the springs are good for .650.

 

yeah thats what i thought...but then the 921s were an extra 300 bucks and were good for the same amount of lift...so i thought that possibly i was reading something wrong

 

The PRC's are more than fine for that cam.

I've always wondered why the Comp 921's are so expensive. Do they hold their spring rate longer than the PRC/Patriot gold springs?
