Installing heads today!!!
I'm putting my AFR 190s on my shortblock today. I just wanted to make sure there isn't anything specific I should watch out for. Just line up the gasket correctly, use moly lube on the bolts, and torque them down to 85 ft lbs (I will double check on that), starting at 40 lbs and working up in 10 lb increments. I am using ARP 12 pt bolts.
A guy I work with said I should use sealer on the thread to prevent oil from working its way up. Has anybody done this? How will it affect the torque reading? He is a ford guy, so maybe this is an issue w/ fords. I have never heard of this on head bolts. Thanks. :cheers:

Use sealant on the head bolts not moly lube.

Yes, use use sealant (RTV) on the bolts! It is not for oil sealant but rather some of the bolts go into the coolant chambers. If you do not use the sealant you WILL have coolant leaking up past the bolts! Also I only used 65-70 ft/lb on my AFRs. You might want to check again on that 85 ft/lb. Get ahold of AFR that is what they told me. Also if you have the valve and spring upgrade you might have problems getting two of the bolts down between the springs, I forget which cylinders they were on. I just ground the od of the bolt down until it slipped between the springs. also the washers need to be ground to fit. Just time consuming. other than that, just take your time and pay attention to EVERYTHING!
