question about the motor in my 86 gt

[bubba32]

I have an 86 gt that I've had for about 6 years. When I took the heads off the motor, the pistons looked funny to me. On top of the pistons it reads ".030", but they are also completely flat with no valve reliefs. The heads say 65 289 on them, and the valves measure 1.94" intake and 1.60" exhaust. I know that the block is a late model (it has a B-303 roller cam in it). It has 1.7 motorsport rockers on the heads. The original owner swears that the short block came from FORD, and says it's a RHO motor. My question is have you guys ever heard of this??

Thanks
