*I'll be running this in a '98 motor with milled/ported/polished '98 heads and a LS6 intake. What springs should I run with this? I've heard horror stories about the comp 918s, and someone recommended Rev springs. Can anyone help me? I'm also concerned with piston-valve clearance? I'm new to the LS1 scene, and need some help. Also, I was gonna run this in an A4 car, but now I'm going with a T56. Should I get a different cam? I want to go mid/low 11s NA with this. Any help greatly appreciated! TIA

I ran a .598 lift cam on some 918's for a while without a problem. The CURRENT blue stripe 918 is a damn good spring.

Comp double springs.

Blue Stripe 918's. Or for security run the Patriot Golds.

Use the VHP/Crane dual spring package (includes spring seats, springs & titanium retainers). We have plenty in stock. Give me a call if I can help.

918's should be fine. Patriot or Crane duals for extra insurance.

No PV problems, even with the heads being milled a little?? How do I check this? Any easy way?

There is a way. other than claying I couldn't tell ya what it is. Not too hard but a little time consuming. Honestly that cam is small enough I wouldn't worry about it. Let's see what others say about it.
