Factory cast iron heads and horsepower = vast quantities of dollars. We've recently been getting a lot of requests for iron heads in the 500-600 horsepower range!
Wow really??? What the heck, that is a
lot of tedious flow bench, hand labor and dirty work the way we go about it!
After I ask a few questions about why they require those flows in iron heads I've simply been quoting them $3,800. That is enough money to make us
happy to do the project.
Every one walks away thinking how dog gone good those aluminum heads are looking!
Right now we have our '346' iron headed 450 stroker not quite ready to fire on the dyno........so I guess we'll see what gives.
