Going to build a 383 HSR AFR
I am going to start collecting parts for my 383 build soon and want to get the right parts. These are what I am thinking... https://www.summitracing.com/parts/c...8/applications
https://www.summitracing.com/parts/sca-1-41829/all I am worried about piston slap with the valves as the pistons are dish shaped.
http://www.airflowresearch.com/195cc...cylinder-head/ Do I want the 65 cc or 75 cc combustion chamber?
As for injectors I was told #36 would be good. https://www.summitracing.com/parts/tfs-89036
As for roller rockers, pushrods, roller lifters, I have no clue what to get. Orr89RocZ I wish you lived in NorCal, I'd have you build my engine.

If you trust your tuning i would go forged flat top for nearer 11:1 comp but tune on premium pump gas. Might need to keep it richer and lower on timing in spots but it should be doable
If thats a concern run flat tops with the 75 cc head chamber. That be 9.82:1
Or keep dish between 8-12 cc. 12 cc and 65 cc head would be 10.1:1. This is harder to find tho, most dish pistons are 16-28cc which means more like a boost piston.
