Yes I think so, try a trial fit by just setting 1 head in place first. I know the valves won't interfere with the block deck because the 350 bore is bigger diameter, but notched pistons not flat tops will be needed. And check the mountings for power steering & the alternator, because the threaded holes are in the heads too. Old school hot roders used to notch pistons right in place with a special tool through the valve guides to notch pistons so slightly. The 327 / 302 also has the block deck notched too for the 202 valveThis saves some time & expense changing out all the pistons. Look at 327 high perf pistons to get an idea. 202 / 327 heads come off of 350-365 hp small blocks. If you stick with a stock 350" hyd. cam, valve clearence will be ok. We used clay to check for valve clearence too.
