In some cases, you can use a zero offset lifter with Thor heads. Others will use a .180 offset on the intake only.
This is with a 7/16" pushrod and .937" diameter lifter. Always check for tie bar area interference on the intake lifter.
The only good way to see what your combination likes is to mock it up and physically check it. You are better off if you can use a zero offset lifter.
Thanks,
Keith

We mocked it up the other day and its def. Going to need and offset on intake and I did notice the push rod was really close to the raised part of the lifter where the tie bar connects the 2 I really wanted to put 1/2" push rods in it but I don't think they willclear. Wish I would of put key way lifters in it...lol guess I could prob. Get tapered push rods? Thanks
