Yes those heads can have huge chambers and ya gotta cc them..I had to get a lot milled my 049's to get it down to 118. I think the 049's/781's are pretty close in terms of port desgin&size. They flow well as even a stock set can flow 270 cfm on the intake!

Take a look at the 820s, you may like them better.
