A few years ago, I broke the intake valve head off the #4 cylinder. This may have been my fault as I neglected to change the valve springs.


I just rebuilt a pair with new 'take-off's' early 90's era valves, rockers, springs, locks and retainers. I'll have to look at actual values but the springs were RUINED after a SHORT season of use. We had 2 track visits and only a few street cruises. I set them up .050" from coil-bind based on measured net lift...Used the Comp 308/.625/108 and Standard BS rockers. Seat pressure dropped from like 230 to 180. I couldn't beleive it. There recycled scrap by now.LOL
