Iam going to port a set of heads for my motor just want to know where i should i put most of my time in what area (ie port,combustion chamber,short radius,roof) using SS valves 1.77 intake 1.50 exhaus .TIA.
As ULYCYC stated the power source book has been out of print for a number of years. I can scan the templates for you and email them to you if you want. I will include a scale so that if the dimensions get changed then you can blow it up a bit or reduce it a bit if needed.
Be very careful how you use those templates, some have ground into the water jackets, (floor of the port) (A bowl port will get most all needed flow improvements) I just had a set done locally for $350 not including, crack checking, etc. Doing the complete work including valves, bronze lined guides, machined the guides for PC valve seals, frost plugs and everything painted for $750. Not CNC machined or flow tested but all needed for a street car. Gene
