After removing intake manifold and inspecting side cover discovered #4 exhaust valve stuck open . I had no compression on #4 cyl . I cannot get head off the block do the studs have to come off b4 removal and if so how do you get them off? Managed to get head separated about 3/8 inch can't get it the come loose any further ? The head was off about 15 months ago for similar problem just before I bought boat. Any advise would be appreciated !
