Re: Which Head Would You Pick?
I like the TFS high ports , but they bringing out CNC machined heads like AFR have been doing the last few years...The difference with 165 and 185 is the inlet volume in CC plus the valve size.. Keep in mind with 185's you need to notch any std piston for valve clearance..The TFS/ twisted wedge heads are deeper and generally don't requre piston notching..A lot depends on total package.. There's NO point in fitting any heads that breath much better than GT P's if std manifold is fitted..Even Explorer type unless ported..If forced induction is used then heads like the TFS R series can be used as velocity is not an issue with forced induction...I'd tent to use total package like the Holley systemax or TFS. Edelbrock package.. They have put some work into these combinations, there's no point in being a pioneer when these guys have it a million times....A cam over 220 / 530 lift is getting serious so top end street heads inlet etc can be used..But keep in mind power under 2800 rpm will be wanting..A 3:7 final drive and 9.5 comp help keep torque up to reasonable pulling power under cam ...
Don't be afraid to try something new. Remember, amateurs built the Ark...Professionals built the Titanic!
