You need to run .002 more piston clearance and .002 more ring end gap with filled blocks. The block probably should have been bored if you were going to go block fill.
When Dan Whittmore did my block he let the hard block cure for several months with a torque plate torqued down on each side. Said you will hear the pistons a little before it warms up. Should have .006 clearance.

Hey Jim

Jakes 434 is filled and he has run it for the last 4 years (untouched) all over hell. It has never overheated. He has gone on 2 hr one way trips multiple times. In the next few weeks we will freshen it up with a hone, new rings and bearings. Jake wants to spray it more this year. Haha. What's new.

Concrete cures in 28 days. What advantage is there in letting it sit for several months?
