Setting installed height

Yes 2.250 intakes, 1.88 exhaust. These are PCE big block Chevy CNC ported 360cc heads sold by speedmaster. They are for an engine I put together for my boat. 496ci and a single blow through turbo. I am copying a build Richard Holdener did and he previously made around 900hp with less displacement and this head. I will be using less compression and pump gas. Should still be fun. Sorry, in my op I mentioned they were brand X speedmasters I didn’t mean to mislead anyone.
