Preventing Valvefloat
 

I've been reading up alot on hyd roller cam profiles and valvefloat. I'm a little worried about my setup since I'm on the low end of recommened spring pressures.

355 SBC
AFR 190 heads
224/230 .537/.511 112LSA hyd roller
Morel vertical bar retrofit lifters
Smith Bros .083" 1 piece pushrods
Crane 1.6I and Lunati 1.52E widebody roller rockers
Manley Stainless I and Inconnel E valves 2.02, 1.60
PTV clearance I .246", E .229"

Isky #6105 dual w damper springs, 1.430" OD, 1.120" CB, 330lbs spring rate,
Seat 135lbs, Open 315lbs @ 1.260", 1.812" IH.

I'm breaking in the new drive so I have not had the motor WOT in the boat yet. On the dyno there was no float noticed but I feel under extended WOT runs on the water it might be different.

With the 23p it's gonna max out in the 5600-6000rpm range.

What do you guys think? Should I be allright or for saftey shim the spring pressure up?

Thanks for the help!
