was going to get on with more stripping today.
the 6mm allan bolts that hold the headers in.....i got 4 off but the other 4 are rusted to booogery and rounded off then i tried to remove them.
whats my next option? can i drop engine with headers ona nd deal wtih the bolts once engine is out? am i looking at drilling them out?
cheers

yeah i thought as much......worried about being to harsh and cracking the block
over worrying? :-?

Having just had a run-in with some reluctant bolts myself, I can pass on the tip which solved my problem: get a blowtorch on the case surrounding the bolt for a couple of seconds and they loosen up remarkably well.

yeah the other 4 moved easily.....i dont think they will give up a hughe fight...........its just getting a grip on them somehow

Beware of those eezi outs hardened steel is brittle break em and nothing drills em.
Read somewhere about welding nuts onto end of exhaust studs - heat and extra grip will do the trick.

Loads of plus gas on the remaining bolts, use a syringe to squirt it in/on, at least over a day or two, hot engine and smack a torx in there and try that.

Impact wrench, loctite freeze-out and heat. Failing that drill and thread insert.

Just had the same issues with caliper bolts, i went to screwfix and bought a set of stud extractors for £3.50 and they worked a treat, just start off with very small drill bits and work your way up gradually using cutting fluid gets the best results.

have you got a pic of the seized in bolts to show what the access to them is like please?
