Heads had 1.88/1.60 valve installed years ago, so trying to make the best of what I have.

Seems like not a lot of focus on the exhaust side here, but just to be clear, can I take out the speed humps in the roof of the exhaust ports (sorry for the upside down pic).

Show the 'all out' on the exhaust.
If you blend the bump... do not lay the ssr back, go mostly straight up off the 60, and just lip the top of the ssr. You dont want the roof and floor to separate/ loose velocity. Total shape of the runner is important for both top and bottom to follow the same angles n shape .
