I am building a 5.0 I am looking for some minor upgrades to add more horsepower for the build and was wondering if anyone knows info on piston to valve clearance with my current setup

What I have below is the current performance stuff i plan on using and am looking for info of what other internal motor parts i can add for more HP roller rocker arms etc??? also anyone point me in the right direction for new springs and hardened pushrods for this as i think i may need them?

Also, what do you guys think about the stock gt40p heads? what could i do to upgrade them for better performance bigger valves?


4 barrel high rise intake
block is a 5.0 ho
heads are stock gt40p heads
camshaft is lift .528/.533
dome pistons L2249N


Really questioning PTV clearance with the heads camshaft and the pistons... Any advice is greatly appreciated.

You are going to have to measure this for yourself to have any good answer at all.
I'd use the clay method so just do a search or google it up.
I always like .100 PTV clearance but on my current set-up I have about .080 which I can live with as it an SRC with lots of valve spring pressure......
