Farmall Super C head

pafarmall · Jan 27, 2014

I have a two part question: Is a 251172-R1 casting code head the correct head for a Farmall Super C or is it off something else? Does anyone have an opinion on how much can be safely milled off this head? Thanks in advance. --Rob

What are you trying to do removing material from the head. If you want more compression get some RED POWER SLEEVES AND PISTONS you could take 30 thous off the head. Then ya better go with a 12v system and a good I-H dist. Check the dia of the sleeves at the bottom where the o-ring depending on the block you could go with the 3 1/4 sleeve giving you around 135 ci in and with 240 gov spring get around 30 pluss HPand turn 2100 rpms.
