WTF am i doing wrong. Rocker issue

Putting my 3.2 back together after re-ring, and head rebuild.

At the point of installing rockers. Cam timing is done, and started with #1 exh. rocker so i could measure valve to piston clearance as per Waynes book.

Once #1 exh. rocker is installed, engine will not turn over as that piston starts hitting the valve. Engine rotated fine prior with just the #1, #4 intake rockers installed.

I've installed #4-5-6 exhaust rockers with no issues and engine rotates fine. I've measured the valve to piston clearance on 1-2-3 intakes, (4.25mm-4.75mm)

Where should i start looking ? I don't know what would cause this. I have to assume cam timing is not correct.
