308 or RHS on a 408

TheDeputy said
Hi Guys,

I'm planning a budget 408 360 stroker build.
I was thinking about using the new indy RHS head. However I have a chance now to buy a pair of 308 heads locally. I expect they need to be gone through totally.
Which head would be best (without porting and stock valve size) for a budget 408, mostly set-up for low end torque, four speed 3.23 rear axle.

I don't have a cam yet, and I might be using an old edelbrock D66 dual quad.

Thanks,

Antoon

Is that intake real restrictive? If it is, then use the 308 heads you'll save money. Complete heads should run about 650-700 with GOOD parts.
Now if you want power, leave the 308 head alone...with NO porting the RHS head should be at least 30HP better and probably more like 45HP better unless you use a stock cam.
A really good cam for the 408's is Comp's 275HL...MONSTER TQ and a little bit of pep up top.

I haven't poured an intake port sorry guys.
