Should I upgrade my springs
I have the older AFR 195 heads with the 8020 springs and stock 1.5 rockers
This is my cam:

I'm doing some intake porting to get my RPMs moved up higher. I am going to set my redline to 6,000 at the track.
If so, what springs would be better for my combo?

Re: Should I upgrade my springs
If you're down to that level of detail, I always recommend installing the springs recommended by the CAM manufacturer. Cylinder head manufacturers always install springs that will work reasonably well for many cams of a certain design (typical flat tappet hydraulics, flat tappet solids, hydraulic rollers and solid rollers being the four "usual" categories they offer springs for).
Cam manufacturers know what their partiular grinds really want, though. They can tune the spring selection much more precisely to work well with it. Look through any cam manufacturer's valvespring section of their catalog- there's a ZILLION different springs in there. That's not just because they feel like carrying all those part numbers on their shelves and making their own lives miserable.

Re: Should I upgrade my springs
My AFR 195's are from 2005.
I have the 8017's.
When I had those springs on my 383, I revved it up to 6500 with no problem
That's probably what you need.

Yeah I was looking at the 8017s. Problem is it will cost me about $300 to change over to them.... Kevin91Z recommended some Manley springs, I haven't priced those out yet.

Best to ask AFR.
With Manley springs, will you have to change cups and retainers too?

Re: Should I upgrade my springs
I've got a brand new set of 8017s that I pulled off my new 165s. Never run. I had to go will lighter springs as I have a hydraulic flat tappet. I have the springs, seats, retainers and keepers. If your interested, make me an offer.
