It's a good idea to gasket match ANY heads.

I am assuming your talking about the lower intake gasket to the head...I used the Fel-1250 and it pretty much is matched right to the head...you might have to make a snip here and a snip there...make it a clean install...

Good Luck

I disagree.

I wasnt about to grind my $1300 heads to match a $20 gasket.

the heads are designed to flow, gaskets are designed to seal.

I did however trim any gasket material the was blocking any of the ports, as mentioned above.

I agree, don't mess up new heads for a gasket. Find a gasket that actually fits the heads. I had to do some searching, but I eventually found some.

The original poster wasn't talking about porting the heads to match the gasket...but trim the gasket to match the flow potential of the heads...

 

[GroverDill]

that would be gasket trimming, not matching

I'm assuming he meant the opposite...he'll post back...

No I was meaning cutting the heads to match the gaskets. And I do believe if your intake port matches your gasket which matches your intake it will flow better between the the too. Same as with the exhaust. AFR sells the gaskets that match their ports for both exhaust and intake. I was asking because my victor jr. intake is already matched to felpro #1250 i believe. Now if i bought a set with the gaskets i would match the intake to it if i am not already to big. Sorry didn't mean to start a small argument. I know these heads flow great and i didn't want to make the mistake of porting them.

I stand corrected...we weren't argueing...I assumed and I was wrong...


GroverDill said it best: "I wasnt about to grind my $1300 heads to match a $20 gasket."

Actaully port matching does VERY, VERY LITTLE that is info from top head porters.

The AFR's are a 1250 gasket size, if the intake sits too high on the head (meaning when you look in the intake you can see the bottom of the head port sticking up past the intake) you can mill the intake to bring the ports closer to alignment. Always trim your gaskets to keep them out of the ports.
