Ok, I have my 1.9 HO head and I want to bolt it to my 94 LX. Problem: I was at the junk yard today and saw that the pistons have raised edges and slightly recessed valve areas. Will the valves on the 1.9 HO head impact the flat tops of my 1.9 SEFI 94 LX pistons?? I need to know if I wasted my money or that this will work. I am also planning to use the larger intake manifold, intake and headers. Please advise if this will work. Thanks. Erik
