351w steoker problems

hey all if i have a 351w bored to 4.030 with a 4.250" stroke, 6.250" rod length, and a compression distance on the piston of 1.100" how do i determine the push-rod length without buying the checker? I want to run 1.6:1 or 1.72:1 rockers but don't know how much room I have to play with. What style and thickness of head gaskets would I need for safety on the valve to piston clearance it has a stock deck height and unmolested patriot heads, by the way this is my first stroker and by advertisement it is suppose to be 434c.i.d. I would like to have it together by spring if money permits. It has patriot heads and a professional products upper and lower intake with 70mm m.a.f. and 5 speed manual with 3.73:1 to start out, I might go with 4.11:1 later got to drive it first and see. Any help would be great on push-rod length and rocker arm size anything really Thanks

There is no way for anyone to tell you what pushrod will be required without a trial assembly and test fitting various lengths if you aren't going to buy/borrow a checking tool. This is one of the areas that engine builders justify the big dollars for their time to get it right. There is no easy way out to do this correctly.
