Dave, I know you are always super concerned about a tight deck height. 
Most guys should be using one just to help their deck height out. The extra .0196" will help a bunch especially the longer 92 & 94mm bore cylinders.

and get out run by .....I wouldent exzactly want to brag on a .020" stroke... nhra was .014" stroke alowance, I dont know what it is nowdays. I assume this crank brings the cc up to the 1600 mark or very close.so your not leaving any cc's in the dirt. great for class stuff, but like i said I see no up side to it for a stronger street performance car when a long stroke will make more hp&smiles for about the same $$ |

I don't see any reason to get new heads unless yours are blown out or have other issues.
I am doing a quick set of heads for a guy in Canada doing almost the exact same thing you are. Stock appearing build for a notch with a little more power.
Here is what we are doing for his.
Stock case, whatever machine work needed
stock crank rebuilt, rebuilt stock rods,
stock flywheel lightened about 2lbs. everything balanced good.
AA 88mm thick walls, .045" deck height
OE single port heads, I will port them, do a good valve job, flycut for 8.5cr. new valves, and new guides. Single HD springs.
Stock rockers on solid shafts.
CB2232 cam, advanced 2 deg. CB cheap lifters, stock push rods cut down.
1 3/8" header and muffler, or VSpeed muffler.
I might be able to toss another set of heads together when I do his since they will be almost identical.

Maybe I should stroke it as well, 1691!! although this was just supposed to be a get me by for the summer build until I can get all the parts ready for the 2270. |

I am still a big fan of stock OE cranks for this type of engine. Amazing quality, and they are pretty much sitting around everywhere.
