You can laugh, but it works ...

You buy a couple feet of heavy wall DOM tubing with the correct diameter hole for the head bolts. You cut them to lengths that match the head thicknesses under each bolt. If you have access to a lathe you can square the ends so they sit flat. You torque these in place and they will do exactly what a torque plate will accomplish.

I had actually considered something similar. we're only trying to simulate the distortion in the cyls when the heads are bolted on. I'm not too sure that the B engine really needs plates. I do know that the 426 Hemi needs 'em. It's that top- inside bolt that is tricky and the way you torque them.

I used a plate to do my 526 "RB" block BUT, I had access to one. The machine shop that did my block said they commonly used DOM blocks if they didn't have a specific plate

Talk to Chris at BHJ Products. Here is a BBM torque plate with a 4.410 Bore. Due to the "HOAX" and material supplies, torque plates are "Made on Order", so you can adjust bore size if necessary.

Cost is in direct relationship to the level of precision you expect. Just doing one correctly is worth the cost.

Yep, I'm gonna buy a plate and do it the right way. Sent my block to a hot tank as I do not like the result of thermal cleaning. My 400 was really, really, stuck. I had to cut 4 rods and melt a section of the top of one piston to take it apart.
