What aggravates me is, there is a lot of really experienced people on this site that know all these claims coming from the LS crowd are complete bs. I guess they won't refute any of the bs because they are afraid of losing potential customers.

The L92 head, from what little research I've done is definitely better. It is the only head ever casted by GM for a small block that is a good 'bolt on' performance head. Is it better than some of the old stock Ford stuff? Hard to say. But if it is, it isn't enough to justify the cost and hastle of swapping an LS motor in just to be able to use them. They may be a little over $1000 for a pair, but for the same price, you can buy an eqivalent head for a sbf. Keep in mind these guys are still paying upwards of $2000 for a used motor. For around $1000, the average person can build a stock short block sbf, install the equivalent heads, intake, carb, cam kit, and have the same performance for the same price without the hastle of a hybrid motor swap.

The good thing about sbfs are the stroker kits are really cheap. When you get ready to add more ci, you definitely have the cost advantage over the LS motors.

don't forget that we're getting it done with less cubes
