pushrods;
my calculations says;
intake 7.800
exhaust 8.600
does it sound resonable?

How did you arive at the calculation. I do mine using a checker push rods and machinest blueing on the valve tip. Then roll the cam around a few times to check the contact patch. also i check the lift on each valve with and with out valve lash before and after I replace the checker push rods with the new ones

I to am showing world part #073010 for the eight bolts and Manley part #42102 for the washers.To check my geometry I got the plastic gage that manley makes at the speed shop that slips over the rocker stud and you use a feeler gage to check the difference and all seemed to work out well for me.:cool:

turbo2256; i also ordered pushrod length checker but , it came wrong
i cut and rebuild one for myself, then did the same things like you did and here is the results
-7,800 intake
-8,600 exhaust
but i cant find these sizes...
i finnaly spoked to crane cams after 19 minutes of call waiting they say that they have to custom build .....

cylinder head bolts:
first arp package was wrong
second i ordered with the number is wrong
now will order the third.....
today is not my day.....

here is the link it says use arp-135-3603 bolt kit, i already have but they dont fit?!?!?

my engine is mark IV,yep i am very sure cause checked the casting number etc.

yep my heads are merlin,it writes on them, part number etc,is ok

what does this mean?!?
strange isnt it?

I ordered ARP headbolts recently and had to add an extra washer underneath the headbolt's to make it work. I have a mark VI block and the bolts were running all the way to the end of the hole. i wound up cutting an 1/8" off the threads and re-tapping the end. It all worked out fine after that.
