Hello
If I use SP001-16 one set of 16 BTR Platinum valve springs, which rocker arm should I configure? Trick Flow 235 heads use.
May I ask the Retainer that comes with the 235 head, SP001-16 one set of 16 BTR Platinum valve springs Can it still be used?
Is it enough to use Ls7 Lifters?
If 408ci Twin Turbo 1200hp street/strip use,
Can recommend a camshaft?
sorry...I am a novice.
There are a lot of problems.

Bronze or powder metal valve guides?

You would need roller tip rocker arms.
As far as retainers, etc, call BTR
