Howdy, first time poster here

I've got a chance to get a good deal on my buddy's car that supposedly got some bent valves. I was curious whats the chance of 'just' having bent valves and not having them screw up the valve guides?

I was with him when it died, we were in second gear, lugging the engine right after going around a corner. The motor acted like it died, made some ticking noises(lifters? probably the valves...) and shut off, now it won't start. The tensioner is kinda screwy looking, I'm thinking there's a slim chance that maybe one of the gears slipped a little so that the valve timing in relation to each other is funky and not allowing the motor to build compression.

I was also curious about whats involved in a head swap on the car assuming I can't just put new valves in, and lap them. What parts would I need to get it done in an afternoon? I'm thinking headset, turbo gaskets, timing belts and head bolts/studs? I'd probably do spark plugs at the same time and all that.

Tensioners
? How many are there?

I've got alot of engine building experience, but I need some specifics on head interchange. Is there any difference between the turbo and non turbo heads like valves, valve seats, compression ratios, etc?
 
Are the 2g heads/ cams the same, or an inprovement over 1g stuff? Are they interchangeable?
 
The cams are the same but the head, intake manifold, and TB are different. The 1g head setup outflows a 2g setup by a considerable margin. It is a common upgrade for 2g guys after a decent amount of bolts have been done. Its not terribly difficult to do but there are some other things that are needed in addition (1g coil pack, water neck, CAS ETC). Here is a link detailing the swap:

I registered, thanks for the referral!

Back to my original question, I'm kinda stuck, are the turbo and non turbo heads the same, ie interchangeable?

I appreciate any info I can get, thank you
 
By going through the old posts and stuff, I've found out the difference in a turbo and nonturbo head, thanks a million guys. Will a little luck an a prayer, I'll have a DSM within 2 weeks
