The Blacktop piston may be very various, to accommodate for your more substantial chamber the dome is significantly increased with minimized flycuts. The exhaust flycuts remain existing but much more shallow and only the middle intake flycuts remains but even which is only a little flat round dish machined out.
The collector design is your typical straight wall tube. To develop a reflective wave the at the conclusion of the collector it should open into your ambiance, and NOT into your normal tail pipe.
