What is the MAX lift for stock Chevy 350 heads?
depending on the type of head anywhere from 550 to 600 NEW ANSWER- YOU said stock, so in that case anything over 400 lift will cause spring coil bind, and brake the spring. NEW ANSWER- somewhere between .450 to .500 should be max lift before any binding on 87+ heads, stock lift is between .417 and .430 with 1.5 ratio stock rockers

What should you do to the heads on a 350 Chevy for a cam with 292 dur and a 501 lift?
I wouldn't be so worried about the heads as the pistons. Make sure you have enough clearance so that an open valve won't hit a piston.

Can you put new performer heads on a stock 350 block?

Can I use a camshaft with a 488 lift with freshly rebuilt stock 462 double hump heads on a 350 without getting bigger springs?
Yes you can you can to a cam with 501 lift that,s the maximum for a stock gm head. You will also have to change your torque converter or it won,t idle unless you have your foot on the accelerator.
Can you run a Chevy 350 cam in a Chevy 305 with stock 305 heads?
Yes, but running a 350 cam with 305 heads is not effective,you need to run 350 heads as well. In order to benefit from a 350 cam you need something to flow that extra fuel and air, so using 350 heads along side of the 350 cam will be the cheapest and best choice. HAVE FUN!! A 350 head can physically bolt onto a 305 block. However, 350 heads can have the valves extend into the cylinder and contact the cylinder wall (even with the smaller 305 cam). The 350 cam in the 305 with stock heads will work. You wont want to use 350 heads you will lose compression due to the largers combustion chambers.
If you put a stock stle rocker arm with a longer slot on a 350 will you have to check for valve clearance?
No, It does not change the ratio of the rocker arm. ( lift or duraration ) They are designed to keep from cutting into the rocker arm stud if you have a 500 lift or more camshaft that's it.
