3836850 is the code for a standard USA truck 261 head (54-62, low compression).
The Canadian Pontiac 261 might have had a high compression head, but the Canadian truck 261 and the USA truck 261 had a lower compression head than was used on a 235.
The person who asked about a "high compression head" on a 261 might have been referring to a high compression "848" (3836848) 235 head (1956-1962) that was/is often adapted for use on a 261 (by drilling 6 additional coolant passages in the head).
