milling iron heads

[cas3]

i'm getting peer pressure here!, most my friends think its nuts to spend the time fooling with stock heads, all say get out the speedway catalogue and order up some fancy aluminum heads. this motor has a merc crank, so 255" stroker already, aluminum looks fancy, but about 800 with studs, and more issues with corrosion, i thought some milled iron heads sounds pretty easy. i think i will put the iron heads on and see what they measure for starters
