Looking for a set of EQ heads for a future project I stumbled upon these on ebay. I`m on my phone so I can`t post a link, but the listing even includes a flow chart that says these heads flow almost 270/200 out of the box as tested by Indy cylinder heads on production 1.92/1.625 valves! They even make them in LA style with the exact same ports, but set up for the shaft mounted rockers and old intake bolt patern.Oh and the spring pockets come already set up for 1.50 springs. Sounds like a real winner for someone after all out performance; a pair of bare castings can be had for $700...
