Fix my W2s or go with RHS heads?

Headers are 1 5/8 primary to 1 3/4, not 1 7/8.

The more I think about it, the more I think I should just stick with the W2s, ported or not. Hopefully there is no damage beyond the suspected valve, if that's what the noise ends up being.

Guess I'd probably be going backwards by switching or would at least be closer to the limit with the RHS heads. I can always port the W2s for more power, put a bigger cam or carb in, better converter, more gear and on and on.

Thanks for all the input.`
