GT40 HO heads

[JaredOSU]

What is a reasonable price for remanufactured GT40 heads? Its for a 351 windsor.

I have looked for the GT 40p heads, off an explorer V8, they can usually be found on ebay rebuilt for a decent price

There are GT40P heads for sale on ebay for 240 a piece. I dont know the difference between a regular gt40 and the p versions, but those were the ones that were suggested to me. Ill be buying heads soon for my prostar restoration.

This pretty much breaks it down.

My firend bought two rebuilt GT40P heads about six months ago from here:

http://www.tristatecylinderhead.com/...products_id=40

Their web site may say they have them in stock but call first.

They build to specs (after contacting you for confirmation of specs). All you'll need to do is use the current push rods and rocker arms. Everything else comes plug-and-play. Request that they drill out the mounting bolt holes to 1/2" diameter. Heads were $300 each and shipping was $40 for two heads (UPS). Took them about 4 days to build. My friend is happy with their deliverable. He ordered a gasket kit from Discount Inboard Marine.

Your mileage and preference may vary.

I am triying to get more speed out of my 89 Prostar. I was told by Discount Inboard Marine to change my propeller and put GT40 heads on. I buy from discount inboard marine whenever possible. They are good people.

A new propeller will be the best bang for your money, what is on there now, I will be trying an Acme 541 this weekend on my 89.

I can confirm the above as I just purchased and installed GT-40's on my '88 Tristar 351 at the end of July from Tristate. Pricing was $349 per head which included machining the holes to 1/2" and brass freeze plugs per my request. The website listed them for $598/pr. but the machining added another $100 to the bill. Shipping was $21 each. The total invoice was $740 as they did not add any tax. I checked out their online page, but called them to discuss and order. Everything was great, didn't take too long to get either. One suggestion, make sure to tell them brass free plugs and also brass internal plugs (threaded), as well as the holes drilled to 1/2". I didn't mention the internal plugs and they sent regular steel ones in mine.

I ordered the complete gasket set from SkiDIM, but as soon as I click confirm, realized that I had the wrong part no. Called them and they straightened it out no problem. After discussing and realizing that I didn't need the valve seals, etc for the rebuilt heads, he put together a gasket set that contained only the items I need for my project. Saved me a few bucks over the 'complete kit' approach. Those guys are great.

Painting up the new heads. Notice the three vertical bars on the ends designates GT-40.
(4 bars is a GT-40P).

Second pic is all buttoned up and ready for some water.

The pictures worked and on the first try! I'm on a roll now.
