I'm on the edge of ordering them now... Just not sure If I should or not. I have the money for them but it's hard for me to let that much money go at one time.
What else will I need if I get the heads and cams? Will I need to get new head gaskets, studs, etc..? I was going to do the PI swap, but If I'm going to spend close to 1k for used heads and stock cams why not upgrade? Would you guys go with an aftermarket intake as well if I do this? I was thinking about the Edelbrock Victor Jr. Manifold. I would have to buy the PI intake manifold anyway. With these heads, will I still have to do the complete PI conversion... the alt. bracket, coolant tube, coolant nipple, etc?
The car has about 130k miles on it... So I'm wondering If I should just wait and get a longblock?
I would love to have these heads and cams though. It's always been a dream for me when I was a kid to have a car with a decent lick while at idle. Especially with my LT's and Electric cutouts that will be here shortly.
Somebody talk some sense into me.

Definatly need some new head gaskets but i dont know about new head bolts. but with 130K miles on the clock, i would just save up and just buy the longblock. that is more practical in my mind. because then you arent paying for the labor to do the head swap and you just add your accessories and go. and if you ever want to do power adder, you can just buy the power adder and go and not have to worry about the bottom end going out. and regarding the intake manifold part, get a trick flow track heat intake manifold with the dual 57 mm throttle body inlet so you can run a dual blade or hollow out that elbow and run a monoblade throttle body. just my opinion.

I would be doing the labor myself...
A blower would be nice, but I'm stuck with my spray for now..

Yes you need new head bolts. Just get stock TTY bolts until you get a built bottom end. You will need a new set of head gaskets get tri metal felpro. The hardballr and edelbrock are the 2 budget intakes I would suggest and trickflow for a mid budget intake. Logans and P-51 are great but more then you need. I have Trickflow and love it.
I am buying my stage 3 heads and stage 3 blower cams from cushmans at the end of the month. Jim is a great guy and is on this forum if you need advice. Register on the cushmans site!

I'm not exactly sure what all you have done oxford, but isn't stage 3 overkill??
I would like to have a more aggressive cam than the stage 2, but I'm not sure If It would hurt me or help me.
What kind of HP gains am I looking at here with LT's, heads, and cams?? 60-70rwhp?
Is it still going to bump my compression up to 10:1 ?
I'm pretty sure I will need a tune correct?

I have a forged block bored .020 over, full exhaust with longtubes, trickflow intake, procharger F1a with 18lbs pulleys (sitting on the floor in the garage). Nope not an overkill its actually not enough but I am doing this on a budget.

since its a full swap you are going to need a tune, and not a canned one unless you are using that to get to a dyno... some people on here have said that there compression went up to 10.5:1 but i don't know much of a difference that .5 is. also, the problem that i facing at this point, is that it does bump the compression up so high and people say that isn't good for forced injection like turbos and superchargers so i don't know if i actually want to go PI or not

I thought you had to be .030 over to go with the stage 3 heads? Or is that just Patriot?

I guess it depends on what size valves they use in their stage 3s.
