496 aluminum head choice

plenty of heads out there..

.650 lift hyd roller
800-950cfm carb
dual plane intake
nothing over 6000-6500 rpms
2500 stall t400
heavy 4000lb vehicle
4:11 tearing

looking for torque

been doing research, AFR's look good, edelbrock RPM's look good, patriots are priced right..

got about $2500 for heads

any suggestions?

Pro-Comp or Patriot heads, 280-290 runner oval port (actually a shorter rect port) are very good heads and will do the job for less money. Pay attention to correct spring pressures and push rod lengths.

I have sold/used these heads for years and had NO problems.

Well First and fore most THANK YOU FOR YOUR SEVICE!!! Its not easy in the middle east for sure.. I too have a few family members still serving, one just was redeployied on the USS Rosivelt aircraft carrier. Back to he heads.. If you have a specific cam you are wanting to run and you decide to buy the AFR heads, send AFR an email notfying them of what cam you have and they can set you up.. The valve springs they advertize may not work for you specfically, so best to contact them...Your best to spend more of your budget on heads and a good cam...thats where you gain the most...
