To swap heads or not...

My kit should be finished in the next month and I'm battling with swapping heads or not. The car is currently bone stock. Besides the turbo, I'll be swapping the intake out for a fox-style Cobra intake with a ported lower and a 70mm throttle body. I've read quite a few times that I should change the head gaskets (to Felpro 9333 pt1) and throw in some ARP bolts to keep from lifting the heads and/or blowing head gaskets. Should I throw the heads back on with the new hardware, or should I save for another month and pick up some GT40s?

The plan is to run 8-10 lbs while I save up for a built engine. If I don't buy the heads now, I'll be saving for a set of aluminum heads when I build the engine.

My main reason for wanting to swap (even for GT40s) is I don't want a dog. I don't want the heads to be a limiting factor with the setup. I also don't want them lifting off of the block. I don't know. Maybe I'm just thinking too much.

Is it recommended to swap out the head gaskets on a stock block with 8-10lbs?

Just trying to do it right (within budget).

You know, I didn't want to install my kit without heads either but everyone kept telling me to go ahead, I wont regret it. I'm only running 7 lbs with a Cartech outlaw kit and a T67. I only have an edelbrock intake, 65mm TB, 5 speed, stock heads and gaskets too, and 3.73's out back. Trust me, just by installing the kit, the car will scream. I was ripping my tires loose in 3rd gear. Back then I was running 19 lbers and an fmu. Now I have an 80mm Lightning MAF, 42 lbs inj., T rex inline pump, Manual boost controller and I'm scheduled to have a diablo sport chip installed and tuned on a dyno. The guy who is going to tune the car said I should "at least" have 400rwhp with 10psi. I do plan on putting a top end package from TFS on the car when time and money permits. I have driven the car for 4 months everyday to and from work 50 miles round trip with out a problem, I did end up changing my TFI module and Dist. and my T/O bearing went, so I installed a King Cobra clutch. This probably stems from the car sitting while I was on deployment. Anyways, install that kit and have fun.

those gaskets should be okay with a good tune and that boost level. I'd just throw some ARP hardware on there for cheap insurance IMO

Leave it, work out a tune and go from there. You might luck out and not need anything so you can save the work and money for later. Keep in mind i friggin hate doing headgaskets, i wait untill i have to then do it to where i dont have to mess with it again.

I totally agree, spend the money on something else then head's at this point. Upgrade your fuel system, brakes, suspension, etc...........heads will come down the road when you have the turbo set up all lined out.

ditto, save your money and wait to see if you "need" to change anything
