Hello, I am considering buying am engine for my boat - it has AFR L98 style heads with angled spark plugs.
Will the spark plugs clear my VP exhaust manifolds?
My boat is about 4 hours and about a week away ....
Many do fit with no problems. It depends on the manifolds. The plugs angle towards each other in pairs, so they angle away from the manifold, plus
marine manifolds go up while auto manifolds and headers go down and that's where they interfere with the spark plugs. Marine manifolds are above the plugs.
