bolt size???

ya know it seams like every brand of motor has the same issue of crud buildup in the head cavities so it amazing to me that by now they never made an access cover you can remove to clear out any build up. the water jackets are not super high pressure so there is no reason the head or block cant be cast with an access opening and removable cover.

but then we wouldn't burn up motors as fast and buy new ones, that explains it all $$$$$$
