i got a brand new set of heads they r 2.08 int and 1.6 exh, i need to know what the valve diamiter of the stem and the seat pressure and instal hight and all that stuff, all i have r the heads nothing else,

the engine is hydrolic flat tappied, and has a .488 lift and a 234 duration its a carb motor,
anything else ask i will get you the info u need, i would rather have summit part numbers seeing how i dont like far from there,

 

You'll need to measure the diameter of the stem. Installed height and seat pressure depends on whatever springs you have.

 

thats the thing i dont have then there bare heads im going to build them, just idk what parts to buy, that what i need help with,

 

Buy whatever springs the cam manufacturer recommends for that cam, and install them to whatever installed height they recommend.

 

Take your heads to a machine shop that works on cylinder heads. They can measure them for you. That's the only way to find out what your asking -is to measure what you've got there.
