I'm pretty sure I knew the answer to this at one point but have gotten myself confused lately heh. I'm trying to figure out the visual difference between the BBC peanut and large oval heads. Anyone happen to have a pic of each kind or a link to a thread on the board (couldnt seem to find one in search.. probably because it's too obvious =p).
14081045 castings (off of a 454 85 suburban) are the junky peanut type, right? Is there any use for these at all on even a mild BBC (porting?) or do I have to hit Pick-A-Part for some 781's?

Thanks!~

Dont spend your money on the. If you want a torque motor, go with it. Other than that, go out and buy yourself a better set of heads. Them heads, you will be lucky to hit 400 hp with a port job and 10.5:1 compression. Not worth the money in my opinion. I have oval ports off of a 66 vette. Gotta love them. And only paid 750$ with new stainless valves, 2.19, 1.88, comp dual springs, comp retainers, mag'd and milled. Pretty godd if ya ask me.

Don't bother with the peanut port heads; not much you can do. Flow = power, and those don't have it.

Here's a set of oval ports. This is a 820 casting, which is about a 71-72 402 head. One of the smaller open-chambers, fairly good flow, an all-around good street head.

This https://www.thirdgen.org/techbb2/sho...hreadid=162081 has pictures of my closed-chamber '66 396 702 castings heads, and the Weiand Action+ ports designed to match peanut heads.

The porting didn't make a huge difference with the cam I've got, but I can't complain about the way it runs with the mild cam it has now.

Here's a couple of other threads with the rest of the porting work.
