Head work

[A fireman]

Well it looks like I bent another valve and or push rod so im opening up the engine and tearing down the heads. Aside from the port matching a little grinding and new seals any other suggestions to do while im that far into the motor without going into the block or having to remove the engine. it has a new water pump done like 2 months ago. thinking about the LS springs but im not sure if its of any use without the top end swap.

well here is what I am doing as of this moment:
all gaskets are being replaced, all the valves are being replaced and lapped in and all the push rods are being replaced.

Also forgot to mention im working on a 94 3.4L w/ 105k miles on it

Re: Head work

Take it to a machine shop, get it port, polished, decked 0.020 for more compression. Get new, bigger valves, I don't know what's available for the 3.4, so look around.

Bigger valves plus a port and polish will wake up the motor quite a bit.

Re: Head work

Letz if I was going that involved I'd buy a 3100 top end for better flow. thanks for the suggestion but I was thinking preventative maintenance.

Re: Head work

if you're gunna take out the castings anyways, and you need new valves and a valve job...it's really not that much more to have the extra work done...

Re: Head work

wait, so why did you think you had a bent valve? Did you test compression?

Re: Head work

I assumed a bent valve because it hydro locked and provided the same symptoms it did this time last year when I did bend a valve after a fuel hydro lock from a bad fuel pressure reg. I couldnt afford down time so the diagnosis was rapid to allot a quick rebuild. Testing was done after the initial parts order
