Default 1995 Mustang Cylinder Heads

Ok so I've read around on all the forums for different brand reviews etc etc, now my question that I can't seem to have answered is the size of the cylinder head. I have a '95 GT, cai and header back exhaust. Are 185cc cylinder heads too big for a streetable car? I have a buddy with a built 306 that has 205's, he makes 320 rwhp, and he says they are too big for a dd. I wont be swapping to a 351ci anytime soon, as I would think the 185's would choke that motor.

So for a mild built H/C/I 302 with stock internals, are 185 heads a good streetable head? I will most likely be choosing between AFR and Trickflow

What are you looking to get out of the car?
185cc heads are OK on a 302, as long as the rest of the components match. That being said, they are quite big for that amount of displacement.

How much do you plan on driving the car? Is gas mileage a concern of yours? Are you mainly a street guy, or will this be a track car?

And the most important question... What is your Budget?

I'd like to plant 300hp to the ground n/a and still be streetable. Its mostly on the street, but I'll take it to the track on the weekends most likely. As for gas mileage, I'd like to try and keep it the same, but I doubt it. Thats not really a major concern. I've seen trickflows upper engine kit w/ like a stage 1 cam, intake, and 170cc heads. Those just seemed smaller than what other guys are running

Pretty much all you need. But you will want to get the car tuned as well. Might benefit from a slightly larger cam too (like the stage 2)

With the TFS kit you prolly wont break the 300rwhp mark without some serious homework, but as adder said it`ll be really nice to start with that and go from there later! a 185head is big on a 302cuin engine but can be useful if you plan on high revs,

I`ve had a 308 with the TFS topend before it was a kit with the trackheat intake and stage 2 cam, went 8.28 n/a 1/8 mile!

With a good tune you can get close to your goal with the kit!

The Trick Flow heads and the AFR's are very differant sorts of heads, be careful when comparing.
If it were me I'd use the Trick Flow kit with a stage 2 Cam...

So from what ive seen, 170's are the best for a mild 302. So what about a 351w? Whats the ideal head given the same streetable conditions? Im just trying to figure everything out before i spend all the money. Im thinking a 185~205 would fit the 351? And yes i agree on the cam, tht was what i was going to go with. The only piece to my puzzle im still doing my homework for is the head and power adder(maybe).

Look its a very indepth process to find what you need and want! Streetable to you might not be to someone else! You ask about a 351 185`s would work good for that in some cases! It`s a what when how equation!

I have a 210 cc headed 347!

Depends on app and usage!
