His IC pipe is way to high. 99% of the people out there won't have any clearance issues.
His looks to be at least two inches higher than the dog house.
Not sure how that can be. If the inlet pipe was any lower it would push the upper radiator hose into the crank pulley. There is maybe a 1/4" of clearance there. It's definitely a bit higher than the doghouse but way below the vac block.
