Pro filer 290 vs Trick flow 280

Postby 80iowaBu » Sun Aug 06, 2017 10:44 pm

Getting ready to order heads for my 466 big block chevy build. And I'm torn between these two sets of heads. I have a wieand team g 4500 flange oval port intake, set of domed srp pistons. Factory forged crank, eagle I beam rods. Trying to make as much power as I possibly can. This engine will have a solid roller camshaft. This is for street/strip car. More along the lines of strip car with limited street driving. Either set of heads I end up with will be worked over. So if anyone has any experience with these two castings I'd like some input so I don't start off on the wrong foot.

I liked the trick flow better myself for a 496 I built for a customer, I got them bare no valve job. with some fluff work and a mid 260@.050 they made 700hp. pump gas

Profiler head is good also, depending on how high you want to make power. that will determine what head you need. please post more information. Edelbrock makes a great head also. as far as oval vs square.. I think its mostly marketing at that level.

The trick flows may be 10 CCs smaller , but by there flow numbers they more a good amount more air in the all important .300" to .400" lift range.
If you get them and do not have a flow bench to guide your porting rework then I would not touch a thing about them!
Getting fat flow numbers down in that lift range is far more difficult then reworking the head for bigger high lift numbers!!!
