Thanks guys!!

I don't have one right now, and my head pipes were cut back to add header flanges, so I need to have them made over again or extended, plus I need an 18mm bung welded in one close to the exhaust manifold for tuning (lean/rich)

If all works well/fits well I will have the new pipe made longer to go without the riser altogether.

I assume blocking the exhaust crossover in the manifold under the carb is a good plan as well? I have a valley pan planned in the engine build (Makes sense to keep hot oil off the bottom of the manifold) do they come with and without cross over ports cut in them? (Also seems to make sense to keep hot exhaust off the bottom of the manifold as well)

Summer driving only, but some mornings can be pretty cool/cold.
