I had to open my heads out a bit with a hone as mine bound up on my new cams. One was a new head and one was used. I ended up right on the edge of the Subaru clearance limit and I have 23K miles on the motor and no issues. Apparently when the heads are bolted down some times slight variations in the block can cause this. I've done this with other motors before and I haven't had any issues. It's better to make sure the cams spins freely then to tight. Cams take very little load and run at have that of the crank so oil clearance is not as critical. Just make sure your oil pump can support that little extra flow.

Ive got around 4thou clearance on my cams..........typical #3 rod bearing failure and me reusing the old oil cooler resulted in the intake cams seizing up with debris. Had the head shop clean up the scoring and measure clearance. They said 4 thou is waayy over the limit but they've did this plenty of time before and felt good with me using the heads anyway. Well......with the excess clearance and double oversized valves..........im at about 30000 miles,20psi daily, runnin great, no oil comsumption issues or noise. Actually the quietest suby engine ive personally heard.
Although most "Master builders" will disagree......

I think youll be alright buddy .)
