Yeh I bought their valve spring package too, but I went with the steel retainers, I dont plan on twisting it above 6500 rpms, so I hope they will hold up.
They should hold up.. I was considering going that route but I figured for the extra $100 it would be worth the upgrade. Let me know how your build goes; good luck w/ it.
Hey Ill let you know how things go, on another note with ptv contact, what head gaskets you using? Im a little worried because I have taken .010 off the heads Im thinking either get thicker head gaskets or flycut or notch the pistons for valve clearance.
I am using cometic head gaskets @ .038" thickness. Cost is roughly $180-$220 for the head gaskets alone.. VERY EXPENSIVE, but they are the best ones money can buy. I figured I might as well do it right the first time. BTW I finally got some dyno #'s.. unfortunately they only ran the car to 5K rpm so the rest of my top end isn't listed on the dyno sheet, to it's kind of inconclusive. It only shows up to 440. Jerry W. tuned the car and he said that if they completely ran it, it would make about 450-470 to the wheels, TQ would be about 440-460. This is with a 12 lb pulley, but now is only making 7lbs of boost. so 450-470 rwhp on 7 psi isnt too bad i dont think.
