The Lunati was 520 lift and 320 duration on both sides. I always felt it was a little sluggish at launch, but it had a great top end charge.

Thanks everyone for the great input. Having read through all the good suggestions I realize I've probably been over thinking this and need to get back to the basics.

Gotta get new valve springs ordered as I've concluded I don't want to push my luck with springs that have been in the car for 30+ years.

It's only November and I'm already thinking spring can't get here soon enough.
