Stroker 340>416 Build Advice

Hey all!
Building a stroker 340/416 for my 70 Duster 4spd. Already bought the rotating assembly, getting the SCAT 416 all forged with the dished -20.5 cc pistons. Trying to figure out heads/cam and looking for what others have done or had experience with. The car will be a street car running pump gas so I was looking at about 10:1 CR and sticking to AL heads which I believe would be about a 65 cc chamber. Any suggestions on what heads and cam to use?

I'd shoot for 9.5 to 9.75 compression. I think that is probably about where you will end up with 20.5 cc dish pistons. Sounds like the same ICON forged pistons I have. My 416 measured out at 9.7:1 with small chamber Edelbrock heads measured actual at 65cc's.

I run 91 octane true everyday pump gas, with 30-32 degrees total advance. More timing and it will ping on steep mountain grades in hot summer.

Warm climate here in valley's of So Cal. Not as hot as Arizona though.
