Brainstorming ideas for coolant crossover on Air-Gap intakes

That first part is true, if I upgrade my engine with aftermarket heads in the future I will probably go with the LA intake bolt pattern for the much bigger selection. I could run an RPM intake with no crossover and it would probably stay warmer overall and be more consistent after the engine is warmed up.

For the time being I've thought about just pulling off a heater hose and re-routing it under the plenum to see if it does anything. Wouldn't cost anything and totally reversible.

Khalid: No heat riser port,on E/Q heads... My LA bolt pattern heads,still had a sealed heat riser crossover port...Isn't gonna happen... The heater under the plenum,is interesting...In the 80's,some OEM carbed setups,used "heat grid " gaskets.. Electrical controlled,would preheat the air/fuel mixture for emulsification...Not aware ,of an four barrel application,just some info.
