1.88 intake valves
The heads are milled .050 & I was planning to home port them similar to what I have seen here, as well as increase the intake valve size then pick a more suitable cam.
I am running a summit k6900, I have 3.27 rear end gears to go in & a ld4b intake to replace the performer I have now. The 318 is bored .030 & has about 9.3:1 comp, & 165 cranking psi. Its a weekend ride with a std 904 auto.
I read the 318 cam post & must say I got very confused lol
cheers Pete
