Get 68mm domes cut for your application.

ok..who would you recommend...or can a stock head be modded for the application.....sorry for all the ?s its my first cub build...

gotta-go has got it right....you need to get your domes rechambered/cut to the 421. i believe that both F.A.S.T. and HJR can do it for you.

Stock head can be modified. But a coolhead setup will allow you to change domes easily. I'd recommend NOSS, or any of hte site sponsor builders if you want to talk to a builder about specific dome configurations.

Ok thanks guys really appreciate the info...

You need domes for blaster pistons,Im almost 100% positve you cant rechamber a banshee dome for a blaster piston due to the angle of the piston crown,FAST can hook you up for sure but that PT head might limit you on places to buy from

so do I have to use blaster pistons with the long rod cub build or can I use a regular wisco 68mm piston?

I used blaster pistons with the long-rod serval I built (same block, different port timings). 573M06800 I believe is the part number. Its a wiseco pro-lite 573 series forged piston made for a blaster with 68mm bore.
