Hey guys just wondering when boring our blocks are deck plates needed? Just don't want the cylinders to warp when torqueing the heads down and all the machine work I paid for go out the window.
Ok is there anyone that happens to rent any by chance? The machine shop that is doing the work doesn't have a set. He said he could make them but to do it for one build he said just will add more to the bill.
'add more'.... good one.
as someone that knows a little bit about Buicks and a little bit about machining, and a little bit about automotive machining, and a little bit about what it takes to make a torque plate ( yes, I'm made a couple).....
add 'more' is a little bit overly simplistic.
Also, based on my personal first hand expertise with a bore gauge in my hand a torque plate is worth about 1 and a half thou of distortion in the bores.
Boostedblack87, not to question your engine builder but I had a reputable Buick engine builder machine and assemble a motor for me. He has built stage 2 engines since the mid eighties. I had to take my engine back to him with a very obvious mistake. He didn't notice that my engine was an off center. He didn't install my rods correctly. He had never even heard of an off center block. Not saying that your guy would make the same mistake or build your motor with tolerances like a small block Chevy but make sure that you give him a few guidelines and references.

This sounds excessive was this on a Buick V6 motor or something else?

Make sure the guy torquing the plate knows what your head torque will be. My aluminum heads only take 65 ft lbs as opposed to the 85 ft lbs most use for iron heads.
