If you want 70, stroke em to 383, put on good heads have cams designed to the rest of the build. That should get you there. IMO with stock sbc you will gain very little with exhaust.

.020" sbc head gasket

Is there a .020" sbc head gasket out there that does not need wire spaces cut into the block? I am looking for something that thick for my 383. Mostly so I will not have to deck the block.

I had it supported well under the transom and the keel, as well as along the sides. This hull is very heavy and stiff from the get go, but I took preliminary measurements and checked often.
