I found a 1996 explorer motor that I can get the heads and upper and lower intake. These have the GT40 heads, right? I want to make sure I get GT40s so that I dont have to change my headers at the time. How can I make sure they are GT40s? Aren't there markings to tell the difference? Also, how much should I expect to get them ported?

they will say gt40, i think they have 3 bars on the front or back of the head. i just got a 98 motor and they have 4 bars and are marked gtp on the outside.

If I don't end up getting this set, I will still contact you about the intake that you have

blk40th

no prob. also for porting, ive been looking into it now and depending on how into it you go it ranges from $600-800.

don't the explorer heads(non p heads) have lower compression as well?

you might want to get them milled to bring it back up

blk40th

i got an explorer motor and it has the p heads

Anyone know how much should I get them ported to?

drhoward

the p heads came on later model explorers 1997.5+ I think

What would be a good estimate on how much it would cost me to have Thumper do this? (including shipping and everything)

drhoward

mine were around 6 or 700....I can't exactly what it came to

But he did everything to mine, new valves, springs, port work everything
