Had my Trickflow heads ported, here's the #'s.

.100 73.8 68.4
.200 144.0 94.6
.300 198.6 154.7
.350 223.0 168.5
.400 242.4 181.0
.450 260.2 194.4
.500 278.2 206.1
.550 293.5 214.6
.600 301.1 221.3
.650 302.4 224.5

Intake valve is 2.02 and exhaust is 1.60 Tested @ 28" depression and the exhaust ports were tested with a pipe.

 

What runner volume did you end up with???

 

who did the porting?

 

Nice numbers... who did the cutting?

 

Looks good.

 

Nice numbers!!

You oughta be able to make some good power with those!

 

Those are nice #'s. These new Trickflows will help us LT1 guys with an affordable aftermarket head that flows nicely. You can buy a new pair from Summit for $800 with the $100 savings they have on them. I should get mine back from Lloyd today with very similar numbers. Later Clint

 

I think the intake ended up being 205cc.

I had a local machine shop do them.

 

How much did they run you after the porting?

 

Nice numbers, that's almost symetrical port ford territory with a 205cc runner.
