Hey, I am using Trick Flow Twisted Wedge Heads. They cost about 1100.00. I ported these myself to the FelPro 1262 gaskets which makes the port 1 5/8 x 2 1/8 inches. With a really mild cam, 278 duration .478 intake an .498 exhaust, the car runs 14.00 flat with 3.25 gears.
I really love these heads, they perform much like the 4V Clevelands breathing wise, but have low end torque. By the way, the Boss 351 is the fastest tested ford engine at 14.3 et. My engine has less cam and runs 14.00 flat. So go with the trick flows and enjoy yourself.
email me at
jim_howard_pdx@yahoo.com if you have any other questions. I am shooting for 13.25 with 4.57 or 4.80 rear gears. I do not have them yet but hope to test these before the rainey season begins here in Portland Oregon.
Happy racing. By the way I raced two modern Cobras last night. One ran a 14.85 the other a 15.35 et. Gotta love these Windsor engines! I would really like to try a 250HP shot of nitrous, since I am using a bottom end built for it, but I do not have the guts to abuse the bearings on a daily driver.
