If you don't have a set of the 243 castings, we have brand new GM castings for $395.00 per pair bare.

 

Ok I will keep that in mind. Since they are going to be completely redone I dont think I need brand new ones. I may go that route though Thanks again

 

Which set of your heads would you recommend with the msv4? I am wanting some excellent power out of this engine. All I will have is the heads, cam, headers, underdrive, true duals, fast 90/90 setup, etc. Just wanted to see what you would suggest

 

A set of our CNC ported 243 castings with oem 2.00"/1.55" valves and Patriot Gold springs would work well. They will give you great flow and the most PTV clearance. These run $1095.00 per set. If you are talking about a non-ported head, go with the 243 over the 241 because of the smaller combustion chamber and greater flow.

 

Oh I was wanting ported for sure. Should I go with stage 2 or 3?

 

all depends on your goals....

 

I would think porting stock heads would cost the same as purchasing cnc heads, plus porting stock heads will you get flow chart? purchasing cnc from sponsor atleast you'll get flow chart and you know what ur getting. unlike porting your stock heads and not knowing the flow will make you wonder if anything was left on the table. so to speak. something to think about....

 

That is why I am looking at Patriot heads now

 

Which would be a good head for my 5.3L s10? Mods are in sig. Im just wanting to do a P&P from a local guy.
