As the other guys have said, it's generally accepted not to remove the head unless you have good reason to. I thought your mechanics reason for removing the head was to do the stem seals, which can be done without removing the head but some mechanics preference may be to remove the head. If he is removing the head on a 58k good condition engine just to have a look i'd walk away now before he inflates your bill further. As for upgrading the stock headgasket, what a 'croc of shit' that is. Have you ever heard of problems with the stock headgasket? (unlike MKIII's) A lot of guys in the states running big power continually use the Toyota gasket for good reasons, it's a good quality part. The heads can warp when they are removed, but it's not necessarily the case and there is a good procedure in the Toyota manual for checking the head once it is removed to see if it needs skimming. By my (very) crude calculations by fitting a headgasket 0.5mm thicker than stock, your compression ratio will go from 8.5:1 to 8.1:1 (may want to get somebody else to double check these calcs, like your mechanic) which will result in a slight decrease in performance off boost, but may allow slightly higher boost. Are you sure that is your desired result?

Not done just yet he is doing this between jobs to keep the cost down for me and a project for himself so he can make all the pipework up for my car so when someone else wants a single set up he will use all the parts that he had to make up on mine and send them to the metal workers and have some set up, can't wait to get it back now and all this good weather is doing my nut in lol
Paul is trying to sort out this bad name thats chris has left him with hope he does |
