Thread: Some more top swap questions! Yay!

Miles don't matter a whole lot. Getting them cleaned up never hurts.

And 9/10 used heads will already have a crack between at least one of the valves, not something to worry about as they affect nothing.

the injector clips should be the same, but you also need the l67 rail and injectors, if your junk yard hunting just take it all.

if your looking for jy heads, id at least lap the valves, and change the springs and valve seals. if your planning on rockers or a cam with it, springs need to happen anyways.

then as long as you got em in hand, you can always port them or at least clean them up. inside the ports is so rough. any smooting will help it flow better.

stock casting in the exhaust port they all look like this.



with some time invested you can make em pretty.

diy porting will run you about a $100 in tools. but well worth it. i spent a easy 8 hrs per head. maybe a bit more with the valve lapping.

two 2.25 band clamps, two, 3 inch band clamps, unless you need a cat, then you can weld the cat in and not need the two 3 inch clamps.

reuse the stock head to manifold gaskets. toss all the gaskets and clamps they give you in the trash, all but the cat back gasket, use that one.

yes you need a o2 extension. and maybe a new rear o2 if yours dont come out the dp. or a tune with the rear o2 deleted. you will need a tune for this.

In-car tunes are the best, then you can tweak it so its just right. Reptile is good though, tell him your mods.

id get a reptile tune cause hes about as cheap as your gonna find, and his tunes are pretty good too.

or buy a tuner and tune it yourself. dhp box runs like 250 ish brand new.

I can take as many detailed pictures of the two sets of heads as you'd like! I'll look them over best I can as well. Just PM me with whatever you need, any questions, wanted pictures, ect. just let me know.

are you two local? cause shipping just heads costs about a 100 bucks.

that whole package shipped could hit $150 easy and fast.
