Trick flow noob ?s

I’m sure this has been covered a million times but I need clarification as I’m learning as I’m going

68 barracuda 340, 727

I’m getting close to pulling the trigger on aluminum heads. I’m reading a lot of conflicting info in regards of trick flow heads are ready to go out of the box and bolt on vs a machine shop is required to adjust/tune assembly. So what’s the real scoop? Does that mean all I have to do is swap in rockers? Step by step details are appreciated. Thanks! Trying to save myself $$ and do it myself. I can figure most things out, granted I have all the info needed.



if you buy a set let me know. I have a 10% off coupon from Summit. They will probably be on backorder but they have been filling them rather quickly. Don’t forget to get studs or head bolts.
