New moog springs and my posi disc 99 rear, so after I get all the old undercoating off and redo, the rear will be done. Anywhere I can get a access door locally so I can fix hackjob where someine cut for fuel pymp. Also what is heaterhose modbfor rear springs and whats a normal amount to cut springs?

Rears should have rubber isolators not the front.

When Aaron and I did the front springs on my Berlinetta, they had isolators on them. Wink

I have isoatets so ill be good there. I woukd have got your srings but I got 4 nre ones when I bought the konis.
I would rathet weld, especially beings I wont have a pump in tank, but I lack the skill, and I cant move it to take it somewhere. I realky want it sealled though. I am respraying the undercoating but someone sprayed it all over and way to thick and it loiks like poo poo. I also need to go to jy and get fuel lunes frim a carbed car.

Not worth it.

Best case scenario if you know what you're doing you might improve the HP of a street engine by a few %. Worst case you'll lose HP and torque over every RPM of your rev range by not knowing what you're doing and messing something up.

I guarantee that if you built the two engines exactly the same with amateur ported heads vs untouched castings you would feel no difference between the two. It's not worth the time, money or effort.

If you want to do it, then do it, but don't expect anyone to tell you it's worth doing for your purposes. There's a reason the big head porters get paid big bucks to do a set of heads. They wouldn't get paid that much if any guy could pick up a Dremel and match the gains they see. If you think it'll be fun, go ahead and try it out but don't expect a miracle.

If not wirth it , then not doung. I guess I was reading to much on tgo. They be talking about 30 or more added hp. Alsi. To surface , standard valve grind and assemble, the shopbis saying 309. That average. I already spent 126 for tests and dissasenble
