For the RV-10, you can use the James IO-540 plenum even though you do not use the James cowl - you will need however to do some glass work on the stock cowl to incorporate the round inlets. Considering the cost, the James plenum is dirt cheap compared to making your own.
I used the James Cowl and plenum on my RV-10 and recommend it. For the RV-8 however I did not want to add the required prop spacer to use the James RV-8 cowl. As Iím using the IO-360-M1B engine Iíd like to keep the snorkel intake and not add the separate engine air intake - so just using the James plenum and then modifying the stock Vanís cowl for the round inlets appears problematic.
Iíve seen a lot of nice RV-8 plenums on VAF so I figured there must be a mold or two on the shelf waiting to be used again.
