Nice build!

You’ve got me curious now about the valves. Unless there’s something that makes these like glass, I don’t see what the issue would be, so long as you keep EGT’s in check.

Back in the llate 90’s I was running a 250 shot (2-stage 100/150) on a SBE 5.0. I did work the heads & put in Manley 1.60” exhausts, but they weren’t anything special, just regular old replacement valves.

Only thing I will say is I had a dedicated fuel system for the spray that had race fuel (usually Turbo Blue). Just make sure the EGT’s don’t get out of hand. Beyond that RPM is going to be the next thing to keep in check.

Add: One thing I would mention is be very careful with E blends & juice. They tend to use 87 octane & there is a danger the Ethanol can separate from the low octane mix.
