get the mic out and measure. as far as the value of the parts,,, allot depends on the brand and model of the part. if its cheap china crab then its not worth much. i would say if the parts are quality parts then i would offer 5 bills.

 

what the "mic"? And ok, thanks guys

 

micrometer

 

Craby is right on with this information.

 

Lol. Have someone go with you if youre not sure how to read the mics.

 

Buy a micrometer and practice on measuring different things.

 

Make sure not to buy digital one....man up, buy the real ones.....LOL JK!! If you do get a set, and no one can help ya, swing into a machine shop, and get a quick crash course.

 

ok. thank you. ill buy on tom

 

Btw, how much power will a good set of heads add?

 

depends on the heads and what is added besides the heads. cam, headers, exhaust, intake, valve train all work together or need to.
