Those are probably the heads you are thinking of but all I cound find was the complete engine kits for some reason and not just the heads but that will give you an idea on the other things you will need to go with them. If you cant find the heads only just give them a call and ask for the part number. I believe the # is 800-230-3030
 
which one

whats the different in valve 1.47 or 1.46 valve spring. im thinking 61 cc 2.02/1.60 at 540 lift this is the bolt on trick flow head right they have so many i confussed i dont need the kit cause i already have the manifold. and i dont need anything big. i want something better then e7 heads and how does trick flow compared to edelbrock heads
