I use one of these $3.50 dividers or you can make thin cardboard disks of the ports and grind the head to match, use the gasket to match the entry!. From the pic it don't look like they were hogged out though just a clean up and blend the sharp edges!..
As far as the springs goes, there's only one way to find out what you have and what shape they are in and that is to use a spring tester to measure spring pressure, first to see if they are all equal, second to see if they are compatible with your cam!. Unless you have a spring tester, I'd take the whole pile and take them to Larry and let him check them and come up with a good set. This is the only way to find out what you have. You don't know the history of them, if the motor got parked for long periods at a time without backing off the valves they don't last long, when springs are compressed they lose tention pretty quick!..  |
Yeah I figured taking the springs to a machine shop would be a good idea to see if they are still in good shape. Yeah the intakes were port matched and smoothed no real heavy grinding done to them. They really didn't do much to the exhaust ports though, smoothed a little but not gasket matched. The calipers look like stuff we used in wood shop But the cutting disc templates sounds like a plan what do ya think one every 1/2" or so |
Believe it or not those calipers are damn accurate, you can go an 1/8' at a time if you want. But yeah making discs work good, 3/8" to a 1/2" apart will work just fine!..
