I'll leave the piston/rods combo to Pat, that's his area of expertise. Sounds like a nice combo otherwise, I have used lots of Comp Products and Howards Cams, they're nice pieces, good quality, and they are nice to deal with. I would definitely go with a dual plane for what you're doing. Edelbrock Performer is prob. the most common choice. The Air Gap is nice, but it wont help with performance, it just looks cooler...and it will empty your wallet even more The heads are a good choice. Check with your machinist, or Pat can comment on the machining. I think the spring pockets are OK, but you will prob. have to have the top of the valve guides machined down for that lift. Have good seals installed while they're at the shop, go with the larger valves, cc the chambers so you know where you're at, etc. Make sure you go with the springs that Howard's cams is recommending for that cam. You'll love it, it will be a torque monster for sure! John

I will agree with what Pat said 100%.
I would look at a SRP piston part #142980.
This is a shelf piston.
This piston will give you about 9 to 1 with your heads.
The piston is for a 6.385 rod.
The longest rod I would ever run in a street car with a 9.80 deck would be the 6.385.
If it where a 9.80 deck in a drag car well then I might look at the 6.535 rod.
