stroker motor with port job

[DreamShee03]

So I am looking at getting a 4 mil stroker motor with a dune and trail port job on it. I have an adjustable timing plate and cool head with 22cc domes. I really dont have any way of getting any fuel higher than 91 octane. Is there any way I can run it this way and not detonate or melt a piston. If so what timing advance. Thanks guys

 

Also if i would happen to run across some AV gas would i be able to just adjust the timing plate

i think you should be fine if u keep the compression under the "limit".Also because i have a blaster that has a 2mm stroker and a bbk in it and runs on pump gas.
