ya, i was looking at the valves and they are oversized. thank you alot.
another question, my supra smokes on a cold start, a big cloud of white smoke just for like 1 minute if that. and also everytime I shift under i pressure. does this sound like valve seals?

ferrea valves are really good.

if you want a cheap, effective solution, just disassemble the head (you will need a valve spring compressor, large C-clamp type.) label all the valves, springs, retainers, lifter buckets, shims and keepers in ziplock bags, then polish the valves and lap them yourself (several online tutorials for this, just check to make sure the valves dont have excessive play in the valve guides.)

i saved a good 300 bux doing my own, and all my valves hold 20+inches of vacuum.

u can also do a valve spring upgrade by getting the BBC inner springs from comp cams and install them instead of stock ones. more seat pressure and its about 60 bux for 24 of them (they are sold in sets of 12, hm, wonder why....?)

i have a buddy with some ferrea valves in his 7m head, and they look titties tho.

After doing ANY valve work check the lifter clearances. Even rotating an old, worn in bucket can cause a decent shift. It's really something you should just do anyway while everything is off.

yes true, i forgot to mention that. checked all mine, and amazingly, nothing was out....ended up doing it 3 times just to be sure, but everything was pretty much dead center, a couple on the loose side, but still in spec.

when you check the clearances, make sure to rotate the cams a few times, just to get any kind of play out.
