I run 91 with 10.4 compression,
Tf heads, .044 quench with both shaft and pushrod oiling.
224 Cam, Ivc 38 degrees @ .050
Max Mechanical timing is 31 before it pings.
But that's in AZ Summer 115 degrees.
With the smaller closed chamber modern design aluminum Tf heads they don't need as much timing as older design open Chamber steel heads need. Imo
I think you'll be fine especially with the larger Cam..
