What hp and torque am I making?

Right now the way I have it setup my airfuel ratio gauge goes from 13.5 -13.2 at idle and about 13.8- 13.5 revving it. So the fuel trim looks good. I don't have to pump the carb to fire it up cold or hot. So timing is pretty good also.

Unfortunately no. That's where I went cheap on this. I was going to save up and get the heads reworked or buy another set of aftermarket heads. But I got impatient and wanted to get the cam broke in. Took a chance. Obviously this was the wrong thing to do. So now the engine is broke in and the engine runs pretty strong and sounds healthy. I will now save up to get new heads with the right springs for the cam.

You don't necessarily need new heads unless that is just what you want to do and have the money to do it.

For a street build toy the factory iron is fine and can be made better with some minimal work. If you have your heads checked and the guides and or seats are trashed, then maybe you spend the money on new or find a good used set to use as cores.

If it were me doing a basic low compression rebuild I would not spend a pile of money on heads. If you do need some though the speedmaster heads usually go on sale at a big discount around Thanksgiving. They still would need to be checked out though by someone to make sure they are set up properly.

You can do a basic check by setting them chamber side up and fill each chamber with alcohol, gas, or whatever liquid. If the valve job wont hold liquid in the chamber then it wont seal air either and will need attention. Before installing any heads they need to be taken apart and cleaned well.
