Hi guys, I just found out that one of my heads has a small crack so it will need to be replaced. I am not a motor guy but the person i have working on my engine recommend if i want to upgrade the motor to go with a trick flow top end kit. I guess it would take my hp up to 550. So the numbers sound good but have heard a few bad reviews about lifter noise. Anyone have experience with this kit? Ill post a link below. Anyone have any other good upgrade kits that i should look into? I was mainly wanting to get more of a muscle car idle with a cam and then i need heads. Was hoping for about 450hp but don't need 550 necessarily. Thanks for you help!
