so im building a lq4 based motor for my 99 ext cab silverado and im having trouble with my head choice. I originally planned to do a l92 head and intake swap then a cam and long tubes and hoping id make 460+hp and some decent torque... but then i basically got a set of ported 241's with bigger valves for free (they had to be repaired in the rocker arm bolt holes)... should i just use the 241's and just buy a ls6 intake? would that setup make that kind of power? or should i sell the 241's and buy my l92s?

thanks in advance

 

Honestly the 241s arent all that great at all, They are better when ported but I believe the L92s would out flow them. With the 241s you will not reach that goal, you will be around 400rwhp. With L92s and a healthy cam you will be pretty close to that mark.. But the L92 setup is going to cost you a few more pennies..

 

Ok that's what I was thinking I just couldn't find a straight up answer anywhere
Thanks again
