Valve Spring choice/seat pressure ??

[turbotalon1g]

Ok I messaged Kelford about the springs I have.

I have crower titanium retainers and spring set, NOT BC.

Anywho he/they sent me 2 messages.

First he said yeah they will be fine, then he said wait, you will need our beehive spring with shim to get the 110lb seat pressure.

I told him E85, 35psi and about 500whp on a DJ. and limit of 8kish.

Any reason boost level would make him change his mind on spring selection.
