just bought some heads!!!

ok it was somewhat of a bargain if these heads are as good as they told me.
i got some heads that are fully ported (D shape) and the chambers have been reworked as well. it all looks good, but they need some cleaning up and i plan on putting in new valves and springs.

but what valves and springs do i need? do the springs relate to the cam?
and if so what cam is a good option to run mostly on street, but that has some punch.

i was thinking of going for a W125 or a W130 but i haven't made my mind up yet.

the engine will be a 78 x 94 (was looking for 90 heads, but these where cut for 94)
i always end up with bigger stuff than what i was looking for at first.

and it will most likely run the 48 dells or some 44 idf's in the future

thanks for helping allready
