Default 243 heads

I have an LS1 looking to put a set of 243 heads on when I get them I keep hearing about stage 1,2 or 3 porting.

WCCH would be good out there in California.

http://www.westcoastcylinderheads.com/pricing.html

Other options include TEA and Ai for ported 243s that run a little cheaper than the WCCH offerings. But if WCCH is local to you, it might be a wash with shipping.

Good cam would be something like a 226/230 using EPS lobes or a 228/232 from Ed Curtis (his StreetSweeper-HT). Both would work incredibly well with ported 243 heads.

Jake I think the about the biggest cam he can run in California is a 224 unless he goes with a super wide lsa to make up for the larger duration...if I remember right out there you need atleast a -4 degree overlap to pass smog tests.

If it's in a 1956 F100, do the Cali emissions laws still hold? Is that what this is going into?
