360 build up advice

I would buy them with the stock 1.94 valves.
They are a good head the way they are.
I am still running the stock 1.88 valves on my performance 360 and it pulls past 6500 rpms.

You really want to use the smallest valve possible for most combination's.
I would use the cam you have in the engine.

The cam you want to use is 226 @ 50 on the intake but the one you have in the engine is bigger \\\ 228 @ 50.
The new cam has more lift and 3 degrees more exhaust duration and would make a little more power but not as much as you would think.

If you go with the new heads, look at how much cfm they flow and at what lifts.
Remember that your going to a closed chamber head and will gain compression.
With about 9.5 to 1 I would step the cam up.
I would want to see the flow chart for the heads but as a guess i would want something in this range.

510 lift /// 234 @ 50 but with the LSA ground at (no more then) a 107.You would be best off with a 106 LSA
This will give the most low end torque and keep pulling up high.
These are just numbers to guide you to a really good cam for your truck.


The only questions i have are what is your converters stall speed or size is(12 inch/11inch) and what fuel do you want to run.87/89/91 octain???
