Doing HG's on my Fox and pulled out FP 90361's. They have been in since '94 and upon further research, they seem to be stockers. I have GT-40 intake with Edelbrock aluminums. I saw a Ford Racing set that was pricey, but the ports look huge. M-9439-A50. What gaskets are you using with success. I also run a S-Trim Vortech blower. Had no issues with the 90361's, but if there's something better... Thanks in advance.
