I found these LS6 Valve springs on ebay and they are rated for .570 lift. are they really.570 or are they .550? I wanted to know if they would be alright for the TR220 also? Thanks.

I am using them with my tr220, works fine for me, others will probably tell you they are junk, but i know guys that have used them on higher lift cams then that and survive, i have never actually heard of any breaking. I have no float at 6500rpm so id say they are ok.

 

Ya i read some other threads before i made this one, some people were saying that they are fine and some were saying they are junk. I figured they would be alright from the other threads ive read. I just wanted to get some more opinions. what kind of gain did you pick up from your TR220? what lsa?

 

anyone?

 

I have them on a 222/222 567.567 112 lsa cam and have been good so far

 

you can find them cheaper then that...i got those springs with valves, seals, retainers, locks for $40 shipped!....do a search on ebay for wegner motors

 

its on a 112, i never ran the 370 without it so i couldn't tell you about the gain, it pulls nice though and good torque down low.

 

got any sounds clips?

 

I found them. They only have 3 items for sale as of right now.

 

I got a set $ 40 shipped.
