Rob, thanks for developing a good solution to seal the manifolds!! Do you recommend to put them in together with Phenolic Spacers? Have you tested the Phenolic Spacers, if they lower the IATs? I know that they keep the manifolds colder that you can touch them with your hands after a run. But the intake air is moving by so fast, do the Phenolic Spacers help to reduce IAT's? Thanks.

Regards Bruno
