what ar the best cast iron heads for a small block for under a grand. i was going to go vortec but i am going to spray this thing and they look thin to me

Dart Iron Eagles. Best flow numbers out there from an iron head.

thank you very much this is just one of those things that i always ?ed about to my buds but none of them could help

look here, summitracing.com
for part # PAM-223260035A
those heads cost $969 ready to run and flow 318cfm intake/205 exhaust

Good call Grumpy. I wish those were available when I did my last Iron Eagle motor. It cost me nearly $2500 to get a fully ported Iron Eage 235 that BARELY outflowed these Pro Action heads. Imagine if I'd of started with these instead?!

Jody

who makes those all i get is a price
and it looks like they are bear

The part number above is for completely assembled heads from Pro Topline (formerly Pro Action).

how much low end am i going to loose this is going on a 6000# truck my goal is to be able to beet my cuz at the track he has a 5.3 and thinks that the 350's are junk

Wrong heads for a 6000 pound truck. These things are for large cubic inch motors or serious street/strip set-ups. They flow extremely well in the upper ranges and that's opposite of what you'll need. I don't thing anyone thought they were going on a heavy truck.

Vortecs wouldn't be a bad choice for the application or a smaller runner Iron Eagle or other aftermarket head. You need to keep the port velocity and resulting low end torque up to get that thing moving.

sorry about that i was not thinking. ya big block would be nice but i do not have the $$$$$ i was looking at a set of 200cc darts would that be small enough or would i be beter off with the 180's

now what rpm would the 180's top out at on a 350 with the right cam and do they flow more than the vortec's
