Hp?
 

i was wondering how much horse this stuff would give me, P&P MXE Heads built and P&P Lower Intake Manifold IMRC Deleted and such?

more then what you have now... lol...

if you get new heads you may need new headers...

this is a good site for 6ers...

heads are always a good upgrade...

My advice... when buying heads, get a new cam/cams and all the valves and lifters (if they don't come with the heads) truthfully, I don't think its even possible to get new heads and not replace the valves, spring, lifters etc lol

why would you need new headers?

if the exhaust holes are different

EDIT^
or even the intake for that matter

GREG@SN95 I know you mean well but dude you gotta study up on heads more.

Anyways MXE heads are called that because of their design from the port and polishing and the bigger valves. Your headers and intakes will still align perfectly that is not an issue. When doing heads you really should just get the intakes done and then get a nice cam for your set-up and future plans. That way you save on labor and time once. Hit up super six motorsports or rpm-mustangs.com both hava a ton of knowledge on this and they offer the parts. Plus they won't screw you over like other places will with BS you don't need or doesn't even exist for our 3.8's LOL.

As far as gains go it's hard to say all cars are different. Too many variables to tell you reliably but look for 230-240 rwhp with the h/c/i package easily.

well... I know many heads have different specs from stock...

These I know nothing of... thats why I said he might need headers or intake manifold

greg, good advice on the cam, definatly go with a cam

I would say get new headers too just to get the most out of your engine, its allways a good idea for a good flowing exhaust.

Greg, your thinking of aftermarket HEADS, we dont have any aftermarket heads, So any H/C/I package is just ported heads because nobody makes anything else.

So stock exhaust manifolds will fit.
