    big block chevy head bolts...

    need a bit of advice regarding big block chevy head bolts. according to a book on the subject when fitting the bolts i should use a sealer on the threads, i have a suitable sealer, a loctite product, however, other people say just use a light oil on the threads... i always thought that some threads on these engines go into the waterways ?

    whats the score folks ?

    kev
    i say, anyone for a spot of tiffin...

    Use sealer because std head bolt threads are open into the water jackets. I use teflon paste on mine but you can use silicon also. Oil would go under the head of a std bolt or ARP moly lube with surprisingly,ARP bolts..lol

    Make sure it's sealer that doesn't go hard. The bolts move around and can crack the sealer in use,leading to internal water leaks.. Have fun..

    Its not the bolts i have a problem with its the bloody holes they screw in too

    I use good old Instant gasket on mine and have no troubles but the poxy inlet rubber's are doing my head in at the moment

    Going out there at some point this weekend to pull the dizzy and re-seal the inlet

    Been told to center punch the sufaces and then try again (or not use the rubbers, just instant gasket RTV)

    thanks matey, least of my worries at the mo, had the short block out of the car today and swapped over the torque converter, thought i might put the heads on and swing the engine and box back in, discovered that the position i had the engine in was 1/2 inch to far forward for how i had altered the headers, not a problem as there is a half inch spacer tube on the engine mounting bolts, had a rethink and swung the short motor and trans in and put it where it should have been, then went to put the heads on and found that the bulkhead needed a little bit of adjustment couple of small taps later... sorted, only problem is the engine is so close to the bulkhead that i am going to have to lift the engine forward to torque the head bolts ! all part of the joys of engine swapping, nothing that cant be sorted

    I understand where your coming from after the recent rebuild and having pulled 3 lots of threads and 2 gasket sets later, I had numerous comments about using studs instead of the head bolts but when you have to sink the engine into a tight gap within the bulkhead then studs would be a real pain

    Who wants to pull the engine just to do head gaskets not me (in hindsight tho)
