Hey.. im thinking of buying the head package off importbuilders.com for $500.. supertech valces and ib spec springs and retainers only the lower spring locaters are aluminum. Any one had any experience with them and are they reliable?? How would they compare to a skunk 2 or ferrea valvetrain?? Thanks.

 

supertech valves are good, but ive never heard of IB spec. thats a good price. I dont know if i would trust it.

 

any warranty with that?

 

bump for importbuilders!!!!!!!!

 

yup...........Jeff knows his **** well.
your in good hands

 

just because it says ib spec doesent mean they made it ..... i remember talking to jerry about these and he said a major name company (dont remember the name) makes them for import biulders .... they are called ib spec because they design the spring rates


i would rate it as good **** because the reputation of ib is pretty good

 

IB = The Shizznoodleriffic.

 

jeff is a crook and ripped me off and sent me some rusty *** retainers, also he tried to push some nonsense scam on me to invest some money. go on his website he listed no phone number and doesnt accept paypal, credit cards, or checks. i regret wasting my money on his shitty products.
