1cam lube most i do rollers but if flat moly. i use many assemble lubes.. some of it has to do with how long the engine is going to set . i use alot of ARP rod bolts and studs and SPS crower .bme .others.i use what they tell you to used if stock bolts oil under bolt head and sealer on threaded parts if a open deck block of head bolts if not open deck then oil not sealer oil or ARP lube under heads and nuts .washers...sealers many... RTV only on oil pans and intake side rails timming covers . teflon sealer on head bolts but lower the Tq on head bolts . any block freez plugs get loctie 620. oil s for break in a oil made to work not some mix and hope deal .so brad pen or joe gibs .on pistons .i clean pistons wall s with clean oil till i white paper towel is clean pistons some what dry .i wet the walls before i put the heads on .before i put oil pan on i give the piston pin a good shot of oil

Thanks, Pat. You mention the torque on head bolts when using sealer on some........lets say they call for 80 lbs torque, do you put more or less torque on the ones that have sealant on them?

if the head bolt will give you a 75 to 80 i would go lower on torque only if its a manley or gm bolt then 75 max if arp then tq them were you want with there lube under the bolt head/washers or were the deck plates were tq to the .if a stock or lower grade head bolt and deck plates are used and lets says tq to 80 then buy better bolts or do not use teflon sealer as it free s up drag to tq and you can over pull the head bolt and hour glass the threads on the bolts. there is no need to soak pistons just makes a big mess . i oil the skirt and put some oil on the ring compressor band or taper. rocker arms set in oil if rollers but i wash then out first tray of thinner then blow dry .if steel stamp shoe rockers then moly on balls .push rod tip on rocker side oil on lifter end .if rollers there some thing s i do i soak the lifters .if solid rollers i wash lifters out in a clean tray with clean paint thinner .blow dry .set lifter in a nice oil bath over night .hey thats all i going to tell you any more you will have to wait for the book
