I may have bent a valve in my D16z6 do to timing belt snap. What are my best options.
A-repair current head
B-buy used head and swap it for current.( any performance gained by swapping Y8 head?)
C-? any other suggestions (I am looking to gain performance but on a budget)

If you swap with a y8 head, your distributor will not fit correctly--the bolt holes don't line up. I KNOW THIS FOR A FACT. My suggestion, if your valve is indeed bent, is to get a new valve and keep the head you got. If you've got money and want some more performance, get your head ported while it's off, maybe put in a new camshaft/valvetrain.

To answer your question--there are a lot of things you CAN do. It just depends on what you WANT to do.

With the head off any way, can I bump up compression with different gaskets. I plan to run N/A on the street, and squeeze on occasion, but mainly only the track. I am planing on tuning it with hondata with nitrous controls.

id probably replace the valve. if you have some loot you might be able to find a head in the classifieds that been ported and polished and whatnot for 4-500 bucks. the z6 and y8 gaskets are the thinnest ones made by honda for the d series afaik, so i think that to raise compression without new internals you would need to mill your head. be careful not to mill too much off, in case you have a nitrous mishap and need to resurface the head again.

bump for more info.

I'd personally rebuild the head. Fix the bent valve, do new valve seals, valve cover seals etc.

it would probly cost more to repair the head then 2 pick a used one up.

besides how do you bend just "one valve? inherantly wouldnt you end up bending 2 valves at once considering its a 16 valve head with 2 intake and 2 exhaust valves per cyl?

I may have bent more than one. Not sure yet. Just wanted advice in case that is the situation.
What should I pay for a used head?

just replace the valves, get .5 oversized, get a little headwork will your at it, mil a little.. why not

Go-Cart

Is the added cost of head work really worth the performance gains? What work should I get done to my head and at what price?

xerox445

you cant just get one or 2 valves .5 over... you would need the whole set, im tellin you, just get a used head, spend your money on something more useful, like a turbo kit, or save for a b series swap....

port and polish will help you, no matter if you are n/a or f/i. i dont think you will need oversized valves, but i would get at least a 3 angle re-cut b/c if your valves were bent they might have messed up the seats. i wouldnt pay more than like 150-200 for a stock head, and like 500 or so for a machined head.
