hi
you can use your standard cam pulley with no problems or you can transfer the markings onto adjustable vernier its quite straight forward
take a metal ruler and aline it with the point on old vernier and dead centre of where camshaft goes this is critical so use digital caliper if you have one
once all alligned you can make a mark with a centre punch on the outside face to give you a static mark for timing i have found that this falls in the centre of the tooth if you follow me
i would like to add once the head is all on and everythink is nearly done and cambelt back on rotate the bottom pulley by hand with a 19mm spanner to turn the engine over to feel for valve/piston contact if all rotates smoothly and your ready to start the engine i disconnect coil feed so car will turn over but wont start and i crank it over listening for noises and do this untill the dash oil light goes out then you know oil is in the topend if you get to this stage and all is looking good and sounding great reconnect coil and start the engine it might take a while to start as the turning over with no coil connected floods the engine but does clear and starts
if your using a piper 285 t2 cam its around 16degrees tdc on bottom pulley with strobe light
if when it starts it sounds tapperty this could be down to where the head has sat
about for a while but should clear quickly as the lifters fill with oil
and the golden rule is get it setup asap dont drive it hard keep revs/boost low as i am sure you know
good luck
