We've bought a 2 pair of the small block assembled heads had to blend everything and port them also the vavle guides were way to tight. bought a bare pair and all the guides were about .070 up towards the top sent them back and got a nother set a the distributors cost.
Patriot heads -pics-

Here's some pics of the Patriot heads the second time around, with un finished seats, supposedly ready for a valve job.
Here's what I started with (after re-doing the guides). It's hard to see, but I think one of the problems on these is that the seats are installed with the tops below the floor of the chamber. The arrows show the lip around the chamber where they cut a small counterbore raduis.

This is after boring the intake throats to size and blending the chamber.
