So like some others I am in the process of changing back to the stock HE's.
I have a strategic plan to ceramic coat the stock ex changers to insulate near the ports of the heads to outgas quicker and then leave the inner exhaust tube bare on the outside for emissive puposes to heat exchange from the tubes but coat the shells to insulate for heat.
Hope this is clear and possible pics to follow.
Anybody done this?
Thanks is Advance
Rob
