milling heads for comp ratio increase
I sorta skimmed through these threads so...
Thanks for your contribution... To suit your post I have answered each line:
Are these the oem heads and has this motor been built B 4?
Engine had never been rebuilt as far as I could see, however it had an old DRTC fitted and a hyd cam which didn't arrive until 68 according to what I read, and mine is a 1967 engine, so perhaps the cam had been swapped at some point. Yes they are just the average 318 heads xxx675 casting
in any case B 4 you mill, cc both heads at both ends, your head miller can then set up to even up the cc's for all 4 end chambers.
I don't know much about that, I still need to check all the cc's yet.
So you do have open chambers? too bad no quench
Yes open chamber, closed chamber ones from an earlier 273 would be very nice!
You already have adj rockers and solid cam is ok with you?
Not sure what you mean. Yes OEM 273 adj rockers. Cam specs given in previous post, and my thoughts also
you can blend your bowls yourself
I was thinking of doing some very light work on them but doing too much will eat into the already low CR. I am port matching the intake -heads
B sure your guides are in good shape- I use K line inserts with the inside knurl to hold some oil and use Viton seals
Guides have all been checked and done where required (K-liners). But exhaust guides will have to be redone when I install the bigger 1.6 stainless valves.
If you are going to higher than stock lift B sure to check retainer (keeper) to seal clearance B 4you take your heads apart
Yes good idea!
I'll try and read this thread later
AFB or AVS good choice for your motor
I hope so too
of course all the 318/ 360 comments apply
you can get HP based on heads and rpm
but you get it at a lower rpm with a bigger motor
True... NCS4CI (no cheap substitute for cubic inches).
