For the technical guys. My JHM spacers have arrived and I will be doing that mod as soon as my check valves and valley pan gasket arrive. I just watched the JHM spacer install video and noticed the curved bottom of the intake that sits right over the engine and valley pan. Does anyone have any thoughts, pros or con as to wrapping the bottom of the intake in heat reflective tape to get just a little more heat away from the intake? I realize that the spacers are minimizing heat soak from conductivity but was wondering if tape would help with the ambient heat in that area. just a thought and question for those that are more experienced with this engine.
Some years actually came from the factory with reflecting material. It’s not a bad idea but if your going to put something reflective just keep in mind that you want the profile to be very minimal. Using the spacers creates a air gap. That air gap between the intake and the motor valley is good for a little cross flow. I actually modified my front core support to help funnel air into that area for extra cooling. Reflective tape or covering is good just make sure it isn’t so thick that it greatly reduced the air gap.
Did all of that make sense
yes that made sense…thanks for the info. I will grab a roll of relect-a-gold and do that then.
Don’t forget that JHM also offers this option for the ported intake manifold.
I can’t speak to exactly how much better the car performs because of it but I definitely can’t hurt. Also, considering it’s a pretty inexpensive mod, I’d probably do it since it’s already out.
I’ve actually considered pulling my intake out of and wrapping it. It’ll at least brighten things up a bit in there.

My stock B7 manifold had heat wrap…and then I put it on my JHM IM too. Who knows if it helps, but the cost is minimal and it’s worth a try to prevent heat transfer.
justin raises a good point, the air flow under the intake manifold may do more to cool the intake manifold. the reflect-a-gold will reduce radiant heat transfer from the engine block and not inhibit potentially beneficial convective heat transfer.
…one upper, haha
