I have PF-4 on my 85K20. I'm surprised you found somebody with a PF-4 in stock. They have been on backorder for like over a year now. Get on the Edelbrock forum and educate yourself. It's a good community.

Having run a Pro-flo for 20+ years now (started with the PF2), I wouldn't hesitate to run a new cam on a new PF4 install. On the same token, I would never waste money on a non-roller cam again.
