RB intake gaskets - 11/25/22 01:01 AM
Wilson called to say the intake for my 541 was on the fab bench this week. While we were on the phone they complimented my intake port template and said it was one of the best hand crafted pieces they'd seen. That took me by surprise. It was functional but not pretty in my eyes. I guess they were just happy to see that I marked the sides of the template for head and intake surfaces.
Anyway, that got me to thinking....
I used a factory style valley pan on the old standard port tunnel ram because it was a touch larger than the runner window. Now that I'll have port matched runners I'm going to need a more accommodating gasket.
What are you guys using?
I could open up the pan but it would require cutting into the embossed areas around the port. Potential vacuum leaks.
The old Indy valley plate from the TT440 is still under my bench but that thing leaves a big gap requiring a fat bead of pookie and a bucket of hopes and dreams to not leak. If I could keep it sealed it would allow use of easily ported paper gaskets.
Then, there's the option of a half breed where the port windows are cut out of the valley pan and paper gaskets are used around the ports. There's a problem of dissimilar crush height leading to possible leaks. I have never had any luck stacking paper gaskets on the metal pan. The increased thickness leaves the intake misaligned.
The ports are still smaller than Max Wedge openings but I might be able to get away with those if I don't mind the gasket thick gap for the incoming air to jump. It still leaves the issue of an unsealed valley.
Thoughts?
