Going to do Heads/ Cam. Looking for Cylinder Head CNC Shop

[91RS]

PSI 1511 valve springs. It is a Beehive design so easy to deal with and I could not find a reported failure of their springs. I found plenty from PAC springs.

Cylinder head work is expensive and if you're supercharged, I honestly wouldn't bother unless you're making a race truck and need that extra 20hp.

To follow up on this unfinished project (almost done)
My local ish shop was able to to do some mild work on my stock
heads. I think I'll be very happy with what they did.
I used some PAC springs by trick flow : https://www.summitracing.com/parts/tfs-16915-16
I believe they will work well with my GPI VVT Cam and still be "weak" enough so
that the VVT will still work properly..
Found out last weekend that my Head Studs were boxed incorrectly, so I just got the
new ARP head studs delivered today... Hope I can get everything back together in
the next couple of days...
Then to figure out the tune stuff
