Or don't overdo the head job and stick with 45's with 36 or 38mm chokes for a vastly more tractable 180bhp that isn't lag city, keeping the std pinto crank and rods which will piss this power all day long and be cheaper than anything cossie wise, a tractable 180bhp is massively better all day long than a always out of the power band 200bhp, been there done that.
I swapped DCOE 48's for 45's DHLA, a better carb by the way, stays in tune much longer, getting vastly better torque curves due to higher air speed through carb, the key is air speed I usually ran with 36mm chokes around 175bhp with piper BP285H cam profile ground onto my std cam, and used longer rocker post bolts with extended long pad followers, otherwise they can rip out!!, only had it once, but a 3 cyl pinto is slow!!
