la heads on magnum block
Hasnt this been beaten to death? :banghead: , people posted the flow numbers and if i remember correctly the best factory 2.02 LA head was about on par with the 1.92 headed magnum.
IMO if you have magnum heads, its a waste to go backwards. If you have those X or TA heads its a waste to go to magnums and if you have other LA heads, magnum heads are a nice inexpensive upgrade.
