what head gaskets u go with? how much preload on the lifters with those pushrods? Any intake manifold fitment issues?
Stock MLS .051
Not sure on the preload but the guy who specd the cam recommended them and then fell between the 1-1/4 to 1-3/4 turns to tighten so they work perfect.
I'd reccomend using GM intake gaskets because on the felpro ones I had, the little locators were about an 1/8“ thick whereas the GM ones have 1/16" thick locators. The intake wouldn't fit with the felpros but drop in nicely with some maneuvering with the GM gaskets.
Curious to see what gains were from the 243's
I have basically the same exact set up for my 5.3, and I'm on the fence of doing a 243 swap
I have essentially the same cam 214/222 not sure of your lift and what not
Tbss intake and TB as well and long tubes.
Edit:just saw your lift and lsa on the first page. Mine is .560/.569 111
Definitely do 243 swap. By the time you pay to port and polish the 862s, you end up paying more money for a head that still has fairly small valves. A stock or milled 243 is a much better value and flows alot better
