So….more header talk….this had me scratching my head

So did you stay with 2.02 valves or did you go bigger?
They have 2.08 intake, 1.65 exhaust. They are supposed to be ' race ported ', whatever that means. This is the engine that was in the car when I bought it in 2019. I haven't done anything to it other that pull the heads this past winter to make sure I didn't have any damage due to a pushrod failure at the last race of last season. Luckily, there wasn't any, so I cleaned the heads and the pistons and reassembled with new head gaskets.
