Thanks for your input

I know why a B16 .. but too much pressure for a B18 or bigger
By the way the car is my DD


I have the block built ,, running 12.5 :1 Cp with eagle rods

The head is PP

I have Supertech Springs from another build

Pressure, lbs@mm --- 70 lbs @ 33.5mm
Max Net Lift -- 14.00mm
Coil Bind -- 19.50mm
Rate, lbsmm -- 10.00

I plan on running S2P2 cams
with those springs or should I get the Pro springs ?

my main question is .. I see lots of guys have prob with TI retainers

should I go with

Crower TI
Super tech TI
brian crower steel retainers
New Stock B-Series
New K20R retainer


thanks
