just wonderin who carries valve springs for our cars besides Poston and ATR? Postons "High Performance" springs are only 39.00 for 12!! that dont sound like a high performance price. havent tried Jegs or Summit yet. I think this is what my problem is, a lazy spring on exhaust valve on #5 cylinder. so i seen the 39.00 springs a figured what the heck. BUT are they gonna be worth the time and effort to install?? I need the "best bang for the buck" tryin to stay under, say, 50-75 total. HINTS???
