What do you think of these heads? Buy them or not?

[gruvee87vertgt]

they are

New GT-40's 1.85"/1.54" VALVES

My stang has over #150k mileage.

I can get them for $900-but should I?
Opinions please.

that sounds a little steep for GT-40s, just save a few hundred more and put some AFR's on there or something

 

[bgjohnson]

yeah, maybe uf they were ported or GT-40X heads then I would consider it, but there are better deals out there man.

You can get brand new GT-40p's on ebay for $500 or less

 

[TT91]

I've got a set of ported Windsor Jrs I can have on your door for $800. (OBO) You can find some more info in Summit's listing. A Windsor Jr unported will outflow a GT40 out of the box.

Here's a little comparison:

LIFT____Windsor Jr_____GT40
.400_____204/126_____183/129
.500_____216/129_____187/129
.600_____222/132_____192/129


You can compare more #s HERE

I don't have any flow data for these heads with portwork.

No, that price is steep. Go with some AFR's!

I know AFR's are quoted as being some of the best, but is it true as to how fast the valve guides wear on those things?

 

[blkstangman88]

u can get a pair of gt-40p off a explorer for like $200 max out of a junk yard, then just port and polish them and there ya go.

Hawaii racing in Simi Valley, CA sells aluminum GT40y's for $799. Thats a good deal. Not as good as an AFR or TW but $400-$500 less. They are on the net. I must tell people about this deal 2 times a day.

 

[dastang2]

there is somebody on the classifieds that has a set of them with 80,000 miles on them for 350 look there first

I got fresh NMRA F/S prepped GT40P heads, MAC "P" headers and Scorpion 1.6 rockers for $1000. That price is too high. Buy some TFS TW for less than $100 more.
