Head/ head gasket repair ?s

[berencam]

I have either a head gasket leak or a cracked head gasket(wont know till next week sometime) im currently in disassembly stage and just looking to see if there is anything that would be recommended to be replaced in a 3400 engine with 166k miles. Lifters? pushrods? rockers? Or should i keep it stock to not stress the bottom end. I want to up the performance of the 3400, i have but im aware that theres not much aftermarket available for that particular motor. Unless you plan on spending 3k on a ground up engine rebuild for mediocre hp gains. I would like to start with a pcm tune. What is the best bang for your buck on that...

I spent 600 on a cam and springs and lifters, and maybe 300 on a valve job/head inspection and yes the time and 500 spent to make headers fit a car not intended to fit, and then gaskets to build it... Then my car ran a 13.996@98

Thats far less than 3k

Stock 3400 it would only get a 15.3

I wouldn't call that mediocre gains.

Research this website, there is a decent amount of aftermarket now thanks to Ben.

Do the work yourself and do it all but the headers (just port them a small bit) and you can do it for half that.
While your in the engine there are any number of tricks you can do to make the engine run more efficiently for not much cost.
You don't need to spend massive cash to get more power.
Everything that applies to every other engine applies to these.

There are alot of upgrade parts to be pulled from other vehicles for cheap or free.
And I wouldn't start with a pcm tune,I would end with one.

Well i was kinda exaggerating. i would love a cam swap but unfortunately its not an option for me as i dont have the facilities to do so. So, as far as the lifters that are currently in it, do i leave them alone or change them while its open. what else should i look at.

As long as they are rollers you are good.
If it was a flat tappet cam and lifter you would need to change them.
