Need a little help just put in a new combo in my 1991 Lx. Here's my combo stock bottom end 302 freshend up Lunati roller specs 215/224 @ .50 and 522/522 but I used 1.7 rockers so it ended up 555/555, trick flow cast iron high ports ported the flow 288 on the intake and 185 on the exhaust with 2.02/1.60 valves. For the intake it's a explorer ported to match the heads by TMOSS and it's awesome, 24 pound injectors with a Pro M to match and 70 Tb with a 190 pump. It has a shorty headers and x pipe with dynomax ultraflows anyways car is running fine but was wondering do I need a aftermarket regulator? The plugs look okay but I haven't stepped in it yet letting it brake.
