questions about GT40 heads

c.moser · May 8, 2009

I found a set of GT40 iron heads for sale. The guy that's selling them said the intake side is ported to a felpro 1250 gasket and the exhaust side has light porting. He wants $450 for them. Is this a good deal? Also, these heads use pedestal rockers correct? I want to put together a mild combo for my vert. I have a cobra intake and a 65 mm TB so far. I'm thinking about using an E303, Trick Flow stage 1, or possibly a custom cam. Would I better off with these heads or should I get a pair of thumpers?

the thumpers would flow more, but will cost more also. show him 350 cash and see if he bites. at 450 dollars I would personally save up a couple hundred more and look for a set of used aluminum heads. thats just me though.

I can tell you the same thing as stykythn Thumpers will flow better and $450 is a little to steep for GT40s.

I picked up some GT40s of corrall for like 280 shipped. 450 is way steep, even with the porting.

$450 is steep

I got GT-40P's for $200

I got a whole GT40 Explorer motor for about $450, shipped. I wouldn't pay more than $200 for those heads; maybe $250 because they're ported.

Do the heads have the stock springs or aftermarket ones? This will affect the price.

yeah I forgot to mention they do have upgraded springs. I don't recall what kind at the moment. Think I might just save and get some thumpers or save a little more and get some aluminum heads. Thanks for the input
