Heres a link to the old post, I started a new one as the old one was getting to long and the mods dont like that.

A quick recap..
My cyl head needed repair after bending some valves while doing cam testing.
Head was originally a DPR stage 6 head that was reworked and modified by Racingflow after me bending valves after Dpr had oringinally done the work.
This was a 100% completey ported head that had made 247 at one point in time in its running on my car..
I sent the head to Brad at RLZ engineering for repair and he told me that he felt that he could modfy the alreay ported head to pick up mopre power and thats how this whole thing started..
My last dyno pulls made on a dynojet refleted the wear and tear on the motor as it has over 10,000 miles on it and over 300 dyno pulls and my power had dropped to 236.9 whpand 155 tq.
Heres the current setup as dynoed..
85 mm bore Dart block
stock gsr 87.2m stroke
endyn oil pump
12.5 cr.. All my previous dynos were at 13.5 so that makes these gains all the moe impressive
RLZ modified ITR cyl head with 1mm oversize Ferrea intake valves and stock size exhaust valves
Jenvey 48mm ITB's with 580 cc injectors
Hondata s200
Smsp header with 2 3/4 exhaust stepped up to 3 inch from the cat back
Distributor King dist with msd 6al ignition,blaster ss coil and stock plug wires .
105 oct unleaded pump gas..
This is an overlay from my last runs made on a dynojet to my high run made this week after the cyl head modifcation.
