this is a plate for a14 they are 16mm thick and oxy cut under water so they have minimal warp. if any one is interested pm me there about 100 dollars each and you have to drill your own bolt holes which is easy enough .....cheers
Maybe he has it that thick so when he welds on all his piping and is finished he will get it heat treated and have the face machined so it nice and flat again.
team dat you hit it on the head matey alot of people forget that after all that welding that some warp will occure even if you bolt it to a dummy head like i did . I alredy have some what of a bend in it already about 1.5 mm that will have to be machined , im sure it will warp some more by the time im finished ,so lets say i have 4 mm warp across the face that leaves me with a 12 mm plate thats straight, The head will also be faced so there both correct cheers
