anyone have the GT-40 X heads

I found a set locally and am intrested in them but know not to much about them. Would they work good with my stock setup and still be able to stay S/D. I'll copy and paste the add and the pics....Remember theese prices are canadian


Pair of Gt-40 ‘X’ Heads Complete with Ford Racing 1.6 Roller Rockers. These heads are in excellent condition with very little time on them. They come assembled with 64cc chambers.

$1250 firm with rockers $1100 with out rockers.

they work good, big improvement over stock heads deff, those rockers make the car sound like a sewing machine though.

i run the gt40x's on my 306 with an E cam and 1.6's, and gt 40 intake. good strong combo, not the best but they are still great IMO. should work good with a stock cam and be torquey and won't cut out at higher rpms like stock.

u won't have to notch pistons or anything. depends on what your going for. good bolt on but probably not the best u could get. if your just trying to get a good jump above stock and not go all out i would say yes.

don't take my word, see what everyone else has to say

those r the best bang for the buck on a stock motor.. makes a great difference..

from what i understand, if you run the stock cam or a SD friendly cam it wont matter. Just search for SD cams on here or corral. Should find a graph of what is SD friendly.

I have GT40x's on my car with the 1.6 rollers. They are not at all noisey and make really good power for street use. My car made 257 rwhp through the AOD with my combo using those parts. The price there isn't the greatest though, since you can buy them brand new in the box for $1250 from Summit. If you want the rockers, the deal gets better. They're $315 by themselves.

I run the gt 40 X heads e-cam 1.7 rr . Good head for the money, but alot of better heads out there.

great guys keep the opinions comming

are you talking USD or CDN $$$

they're 1250 US. and then tax.

1250 canadian is roughly 1060 US isnt it?

so $1060 for a pair of 1250 heads and 315 rockers (new stuff)....and then tax....thats over $1600 in stuff (US dollars)

you'll be happy with em at least until you want more power. i run the 58cc

My friend has them and when he tore his engine down for a rebuild found a bunch of valve guides completely wiped out with like 50k mileage on the heads. They are a decent head but theres definitely better for the money. Id try and find Twisted Wedges for that price imo

check ebay- I got a set BRAND NEW from Parkway Ford for just over 1000 shipped. I also scored a set of roller rockers for 165 shipped. all in all I made out pretty well. For the money , they worked the best for me. I liked the 64cc chambers to help lower the compression and make room for boost. Be sure of the models. x303 have 64cc chamber, x305 have 58cc I believe.

GO FOR IT!!

you could find a set of TFS or edelbrocks for 900 US shipped to your door.

they are sold now....I think my friend bought them for his vert

that may be for the better. Watch some of those items with a real close eye...trust me

dean you probly seen the add that this is from....I am thinking trick flow kit is in the near future
