FI heads

Ok guys it's looking like I have to get new heads

Spark plug blew out the threads yesterday on startup and it was already heli coiled by ford once
They say it cannot be done again and that I will need a new head

Not sure if this has much merit yet but got me thinking

So now I'm looking for some upgrades ..... If I'm pulling a head anyway might as well build the thing right and I will be swapping to arp head bolts as well

Any suggestions on heads pistons cams? What would you do with your own money

Keep in mind the car is a rebuilt title, and this is an unexpected expense so I'm not trying to spend a fortune, but I want to do it well

Also I'm not trying to build 500+ hp would be fun but honestly I'd be happy with 350-400 rwhp and I already have a full procharger kit on it with 14 psi pulley

I just want to make it bullet proof. reliable power with no issues.... Safely holding 14psi I'm not broke but really had not planned this in my budget I can spend money just not senselessly

If you are looking for 350-400 rwhp I would just get a set of PI heads that are stock and replace your broken heads, the trickflow heads are awesome , but for what your wanting they are not needed , a set of stage 2 comp cams and stock PI heads is a nice set up for a budget, and I would kick the boost down, 14 psi on a stock block won't last you very long even with a good tune, the most I've seen people push on a stock bottom end is 12 psi and that will be fine for what you are going for , I would upgrade the springs and retainers on the stock heads if you plan to go that route

Boost is awesome !!!! Just make sure your bottom end can handle that kind of power first!!!
