Thanks AJ - gotchya
Mine is the C also... Dah.. You'd think I would have figure that out. I bought mine before the new heads were available though. And I agree, I don't think it would be worth the cost so swap heads this point.
I'm not getting advertised HP anyway because of changes I've made. I run a Holley 850DP, Performer RPM intake and I changed to a hydraulic flat tappet cam because of problems I had initially with valve springs breaking. On a chassis dyno, I pull 444rwhp and 520rwtq. From playing around with different configurations and observing other SPF 514's, I'm not sure a whole lot more can be achieved without improving exhaust breathing. The exhaust system seems to be a limiting factor, unless of course, you introduce something like a blower or NOS.
I now have 10,000 miles on mine and it’s been a blast every time I get in it!! Enjoy!!
