cool head problems

[talleywhacker85]

I bought a banshee, went to put a cool head on and pistons hit domes. I was told could be a 370 long rod or 4 mil. I was told I need to know stroke, deck height, and what kind of pistons. Any help would be appreciated.

with the head off, bring the piston all the way up to tdc and set something there to mark where the top of the piston is. rotate it all the way down to bdc and measure that distance. measure how far the piston sticks out when all the way up, ad clean the top of the piston to read the part number. you might have to pull the jugs to read the crank number if you can't get a measurement
