Its not clear on the heads looks to me like he used bone stock heads... Anyone know how that setup would work if ported stock heads were used.. I would like to jump to 95inchs and use stock ported heads from big boys and of course the andrews 21..and flat top pistons close to stock compression

 

Anyone

 

I think you'll be way ahead talking to Big Boyz for a recommendation rather than lock in
on magazine print. They do it for a living and want you happy with the end result.

 

I just called him he said really any cam even stock will benefit from a ported head but as far as how big a difference will it make he was unsure

 

I wonder how much difference a ported head would help any ideas guys?

 

For a complete build it would help a lot. For a mild cam like the andrews 21 I really
doubt you'd could tell the difference. imo.

 

21's are for 88's. 26's are for 95's ( they like the higher compression.)

 

Your Andrews 21/95" build probably won't benefit much from a porting job, but if you do port them they'll be done; and if you want to change cams later on, you won't have to pull the top end off. I'm running Andrews 26Ns and stock 96" heads in my 95" build, and it runs great. If I want more top end power, I'll install 37Ns.

 

Thanks guys

 

Anyone have head work with Andrews 21 cams or andrews 26?
