360 Advice Needed - Autocross / Street Engine Build

Thanks for all the porting pics, I have a flame shaped carbide burr on the way.

Haven't cc'd the heads yet, but did trade some other parts for a set of full length headers... :)
Once the engine is in I'll figure out heat shielding and how to make them look right. I expect to do a bunch of work on the collector area to get them tucked up tight and a small skidplate for the speedbumps.

They'll probably be about 3" off the ground at ride height...
