Depending on how well the head is actually working, probably somewhere in the mid 50's on power. The overbore to G pistons will only be worth aprox 3hp alone from the displacement increase. Do you have to run a stock air cleaner? If not, play with the intake tube on a dyno for length and size. A reground cam and roller rockers will help you some, then after that you start to get into the high dollar department.

I dont think welding up the pockets in the Heisler head will do a d@mn thing for you.
