i dont even know what they are... but whats the point of ditching the stock heads and spending more $$ on aftermarket heads when i can get the performance in looking for with stock ported heads.... i just read a guys sig on ls1tech taht has stock bottom end lt1 le2 and a medium cam... and hes going 11.9 on motor and 10's on spray... so i should be able to do a 383 on stock heads... alls i want is a mid-low 11sec car... any faster than that is not streetable im not trying to build a race car....
