[quote=“J&J,post:25,topic:38069"”] Lots of good info in this thread. It all comes down to your budget and what parts you have already. Rich Krause mentioned a GM crate engine which are serious bang for the buck. If you already have a stout short block you can’t beat GM Vortec iron heads, 10.5:1 compression and the right camshaft to match your combo [/quote] Listen to that man! The Vortec heads are damn good and cheap. PN 12558060 is available fully assembled for ~$275/head. **[FONT=Univers-Black][SIZE=1] [LEFT]_12558060_[/LEFT] [LEFT]Cast Iron Vortec Cylinder Head Assembly[/LEFT]** [LEFT]• Completely assembled with 1.94”/1.50” valves • Uses bare head 12529093 • 64cc combustion chamber • Straight spark plugs • No heat risers • Requires Vortec specific intake manifold • Camshafts with more than 0.475" lift require machining valve guide bosses and checking valve seal to valve spring retainer clearance • Can be machined for 2.02"/1.60" valves • Rocker arm studs can be pinned or drilled[/LEFT] • Valve spring seat diameter is 1.48" [/SIZE][/FONT] The bare head PN 12529093 is nearly the same price. Go figure GMPP’s prices??? But even if you upgrade the springs, you are still talking less than $750 for a pair of really good heads ready to bolt on. With a decent cam, intake, and carb these heads are good for \>350hp. --- _[View the full topic](https://forums.speedlife.net/t/chevy-gurus-chime-in/38069)._
