just wondering what timing belt cover you guys are using?

ive got a b16 head + b20b3 block... but my mechanic doesnt know which cover 2 use just had 2 rebuld the head after a rock got in there nd stuffed my tensioner...

*note* not running a Timing belt cover atm

use the b20 or b18 one...

b16a is too short & will leave a gap...

the back cover that sits inbetween the timing belt nd housing?

ah, no i was referring to the timing belt cover - between teh timing belt and the engine mount.

for the 'back cover' that goes between the camgears and the head you need a VTEC one...

NB - you may need to modify the lower edges of the back cover to fit the b20 block if using a B16A back cover...

which main studs would be used for the b20 vtec? arp dosnt list a part number for the B20B all they have is this:
B16A: 208-5402
B18C: 208-5403
B18A/B: 208-5404

the 'back cover' doesnt fit to the block - it fits to the head...

B20B block = B18B block except for bore

EDIT: why you changing them anyways? you know that they are not strictly a 'bolt-on' modification?
