LS head milling and plastic intakes
I hate to ask a basic question but since I've not done it, I have no experience to pull on for this question.
Re: LS head milling and plastic intakes
I've milled heads before to get compression and found it to be more trouble then it's worth. I'd either live with the lower compression or get new pistons for the compression you want.
Re: LS head milling and plastic intakes
Also- the 317 head has a 71cc chamber whereas the 243 castings have a 64cc chamber. Did Chevrolet just cast the chamber deeper for the other heads or what? I think I may need to grab a set of 243 heads and start there to hit my targeted compression number since .078 would be a large amount off the other heads.
Re: LS head milling and plastic intakes
If you can get a set of A-B-C quality 243's...start there. If not... .070" off of 317's you will need to cut the intake flange .015-.020". It is hard to tell as the plastic manifolds normally sit high on the head from factory. Cutting .030" off of stockers normally makes the manifolds fit perfectly.
Re: LS head milling and plastic intakes
I'd really like to use the heads even with knowing I would have to mill the intake flange.
Re: LS head milling and plastic intakes
Also worth noting is that with that much of a cut (.050"-.070"), you are probably going to need to flycut the pistons. I flat cut .050" from my L92 heads, and used a .040" cometic gasket and my intake fits fine with NO extra work, but it is a VicJr. I had to flycut too.
