The Felpro PermaTorque MLS seems to be the hot ticket these days, we have and will continue to use it on the RX-7 with great results. The bore size will support the 2.4l platform unlike the Mitsu MLS which would be our second choice.
In regards to the L19 vs H11 question, they are actually the same material just a different name (apparently ARP made up the L19 designation). Also, the pricing on the A1's has come down dramatically so we are able to match the ARP pricing
I just so happen to have both the FelPro MLS and the A1 studs in stock, feel free to stop by
