Slant heat riser block off/delete?

i always block mine off cut a square piece and weld it in, then have it 1/4 of an inch gap under the intake so its not touching, guess what my intake still gets hot from the exhaust ports right next to the intake ports. Still needed a thick heat insulator gasket t help with heat soak, no matter what im always getting my intake warmed up, especially with aluminium intake, with or with out the heat riser.
