Those heads look like they are serious parts. Do you have personal experience with that company? HAve you used these parts?
This is starting to look like a higher rpm setup now.
Any opinions on converting a 2 bolt block to splayed mains, or would stock 4 bolt mains suffice? Would you take 2 bolt mains to 7000rpm?
A stroker crank and 2-bolt caps @ 7000 rpm is an open invitation to cap walk.
To run the rpm a cam in the 250 degree @ 0.050" lift range is going to use, you are going to want all the stiffness you can get. Splayed caps would be a given for me. You might
get away w/factory 4-bolt cap arrangement w/good caps and aftermarket fasteners, but the wider register that the splayed caps can give is a real plus IMO.
