But this was 2 years ago and I guess that company just wanted my money. I also believe I got them from eBay from that copany At the time because they had the cheapest price for all 16 sets

 

Ahhhh got ya sucks that you were lied to. sometimes thats how this industrie is which sucks. People will tell you something just to take your money.

 

jus read most of your thread. i had the same issues with my head built head using bc springs/retainers but with supertech valves. couldnt figure out for the life of me what caused this. but all of my exhaut valves were bent. lost compression in one of the cylinders. the valve that got stuck open didnt appear to cause any damage to the piston. i ordered a new set of super tech valves and the company called me and told me that supertech stopped making those particular valves due to them breaking. anyone heard of that before?

 

the one valve that was stuck open on mine the keeper broke as well.

 

OOOO how high was your RPM cutoff i am going to go down to 7500

 

i was on stock rev limiter. car had about 5000 or so miles on the motor if that. only one valve was noticeably damaged. machine shop informed me that all the exhaust valves were slightly bent.

 

ialso think brain crower sent me Manley valves
