Head Bolt Retorquing
 

When replacing a BHG with a stock or Fel-Pro gasket, has anyone retorqued the bolts/nuts after a few heating/cooling cycles? Did they move at all? I want to determine if these non-metal gaskets crush down a bit after heating a few times.

It always good to retorque them after about 500 miles. And im hoping your not reusing the stock head bolts.....

Bought a set of ARP bolts, not studs. Discovered that 10 of the 14 won't go into the head w/o grinding clearance into the bolt area. All 4 end bolts go in fine. So I used 4 of the ARP's and 10 stock bolts--all just torqued tonight to 72 ft. lb.

I really don't think the ARP bolts/studs solve anything. The stock bolts don't stretch (other than elastically just like the ARP's). The stock gasket crushes over time/heat and that's why the bolts get loose.

Anyone ever BREAK a stock bolt?

yes i had my hg changed on my 87 when it had like 190,000 on it and the bolts were all broke, striped, and streched to shit.

NO !! ......... hang in there !!

toyota really did "blow it" with this engine

wow i didnt know that, bad gaskets or lots of miles then? are studs better?

if you can do the studs do them instead of bolts .

be warned that when studs are on the head wil be a monster to get back on if the block is still in the engine

very old thread...but do the arp studs go in while the head is on? or is it possible to get the head over the studs while the block is still in the car, if you put the studs in the block first? I just got my HG set and studs, so someone respond quick!
