I'm fairly new to modular motors and have some questions concerning the 4.6 SOHC design. I recently purchased a 2002 mustang gt, bone stock. I've been doing some research and have found that the 2v 4.6 has a problem with leaking headgaskets under boost, but it seems that the 3v and 4v motors don't have this problem.
Do the 2v, 3v, and 4v use the same design engine block? (i.e. deck surface, coolant passages)
Is it the design of the 2v heads that causes this problem?
The reason for all the questions is, I am looking to make a good 600-800 whp with this car, probably on e-85 and supercharged, and want it to be reliable enough that I can drive it 100 miles or more if I want to. I am already planning a t-56 swap and other supporting mods for the drivetrain.
Should I stick with the 2v heads or do a 3v or 4v head swap?
