What heads?

[streetk14]

First Streetk14 flow numbers mean little and even less on a street engine. If it was a ideal set of heads was just based on flow numbers why not put 230cc heads on I am sure they will out flow your 195s. I am not saying your 195s are bad heads because I know they perform well and are good quality heads. The reason I sayed what I did is because he asked for an alternative to AFR and in my opinion as for as assembeled ready to bolt on cylinder heads Brodix is the way to go. Like you I am not very impressed with Darts Heads mostly because of there valve job from the factory sucks on most heads I've seen where brodix is about the same quality as having them done at a High performance oriented machine shop such as the one I work at.

Also I suggested the 180 Brodix as opposed to the 200 because it will generate more lowend which is desireable on a street car in most cases.

ertoys what cc intake runners do the dart iron eagles have? And why did you decide to go with a 377? could build a bigger engine for the same price.



The 377 being a destroked 400 means your going to buy crank rods piston anyway why not build a 420+ci engine.

Flow numbers mean nothing for power? That's news to me. Flow bench numbers (through the entire lift-range, not just peak #'s) are a big deal. If port flow didn't matter, we would all still be running "camel hump" heads. A smaller intake runner that can flow as much air as a larger runner is going to be a better street head. That was my point. The 195 AFR's flow incredibly well for a 195cc head. This equals very good port velocity and torque. I've seen a lot of dyno tests that prove it ( a 420ci small block putting out 560hp comes to mind). Throwing on a "big" set of heads will do nothing but hurt power unless they are matched to the combination. I was also just looking at Car Craft's head flow database (www.carcraft.com/techarticles/116_head_chev/). Look, and you will see that most of the heads in the 220cc range don't outflow my heads (except at very high valve lifts). I don't think that there is anything wrong with Brodix or the other manufacturers. Brodix is a very reputable company, but I have not seen much in the way of real-world test results.
