081 heads + cam TBI build need help
Hey guys!
I got myself a nice set of 14101081 heads.
I am going to port them, and put 1.6 exhaust valves on them.
Cam is going to be lunati 20080660 with 447/.471 lift.
I have no idea which springs to get for this and where to get the 1.6 exhaust valves. Would be even better if I could get a set of every moving part for the heads in one place.
I would appreciate links or contacts where to get this stuff.
I will dyno before and after this build.

You should contact lunati to see what they recommend but I'm sure lt4/zz4 springs or cc981-16 would work fine. The lt4 spring maynot require as much additional guide cutting. Cutter can be purchased at summit or jegs from comp. you may want to cut threads for studs or pin the stock pressed in ones.

But that is all they sell. And I need pretty much everything else there is in the heads! And first of all - oversized valves.
Any other links?

Links to what ? Guide cutters ? Spring retainers/shims ?

I found a company that will port the heads for me and cut them for a larger valve. So I don't need a cutter anymore. But I still need everything moving in the heads.
Will this kit fit? http://www.ebay.com/itm/New-HP-Head-...-/221593322925
