I just put the conversion head on, and I was surprised to find the original head screws wouldn't turn in all the way. This left the head loose.

True, I could shorten the screws. But I took a good look at the head and can see the screw holes are counterbored so there's only about 1/32" of meat left on the head at the bottom where it mates with the block. Is this right - or were the headbolt holes counterbored too deep?

I'm trying to get in touch with Bob but the website isn't working for me at the moment.

Engine is an OS 46 LA

That's back wards. Call him at 6am, that's 9am his time, or you could just call him before 2pm.
You may not be up at 6am.
