LA318 Edelbrock Magnum v RHS LAX Heads

G`day Tim,
Good to receive some feedback on the RHS/LAX heads, very much appreciated......

Just a couple of questions if you don`t mind me asking:

How much were the shipping fees for the heads from USA to UK?

Do you happen to know the weight difference between the LAX heads and your original heads?

Were your original 340 heads the early high/comp big valve heads or the later 72,73,74 heads? What level of IMM LAX heads do you have ie big valve/full port etc? Do you have any data/numbers/details to support the power increase you are experiencing with the new heads?

I have seen the LAX heads advertised as having a thicker deck to support additional milling, not sure if this is advertising spiel or not??

I do totally share your concerns with milling the heads, particularly new heads.
However, I wouldn't`t be the first to do it, plus, it may work out very well for my personal situation, (if I get it right and am successful)......

Hence my interest and my research......

Thanks again....
