> [@Viper966](#): > > why not just port match the openings? That would be a huge job, I don’t want to pull the head and intake manifold to do that, and potentially mess up the port design. The stock design flows better than a few self-ported designs I have seen, so I wouldn’t want to do it myself either. ---

That is a pretty sad spacer. No one makes a better phenolic spacer? You could have your own made relatively easily. ---

mark nobody makes a MLS style gasket for your app? i can understand not wanting the paper since it blew out, as well as the desire to not lose anything from simply swapping a gasket. ---

> [@neonglh](#): > > That could be, but I doubt it, that design would lead to uneven sizing, if the gasket actually squished down to make the gap smaller. i got one of these gasket on my crx after i kept blowing stockers. it doesnt squish down very much, its pretty hard. havnt had one leak issue since either. ---

The exhaust manifold gasket is MLS, which is great, but the intake only comes in the stock paper gasket, a felpro paper gasket for the 1g neon (which i’m using now, not even the same shape port), or the plastic one. Its a shame, since an MLS one would be perfect for me. ---

You’d be better off with the phenolic for heat purposes and they hold pressure well. I have tested them up to 35-40psi. No problems. [Previous page](https://forums.speedlife.net/t/runner-flow-question/47555.md?page=1)
