So here is a new question for SBC cast iron heads.
As you may know I am building a 383 low RPM torque engine for my van.
I will be running a mild cam with Rhoads roller lifters with a pair of stock 193 early swirl port heads.
I WAS going to run a nice set of fully roller rockers when I discovered the stock studs were too short for them.
As at that time the heads were already torqued on to the block and I was not willing to pull them for longer studs. So I was running roller tip rockers.
This changed when I discovered my crank and rods had too much clearance and I then tore her down and had my machine shop redo the rotating assembly correctly…
I have to yet reinstall the heads…
SO the BIG question is a two parter:
How good are the stock pressed in rocker studs??
And will a full set of roller rockers be worth anything for an engine that will never see over 5K?
Rich
Also will porting just the exhaust ports help my engine's MPG?
